this is the jeep as it is sitting now



the frame does need a bit of repair at the passenger rear rail, will post pics after its repaired


found a 2nd bad spot in the frame after i took a hammer to the hole thing so i fixed it first



this is the passenger side rail, still needs a bit of work



11-5-2012

7-20-2013

no pics yet, but getting an 8.8 with 4 10 gearing , disc brakes and limited slip for free soon, just have to pull it out


have the body rolled onto its side, has the typical weak spots under it, new it needed work when I bought it so I wasn't suprized when I started cutting out the rot and started tacking in the new pieces








I also have a Cherokee for parts that I robbed the front drive shaft, seats, auto tranny and transfer case, shifter, rad, and a few other parts, will be pulling the front diff out of it before it goes to scrap, im also getting my parents explorer for parts that im taking the rear diff out of and a few other parts from it soon to


7-24-2013

picked up a complete used 1 inch daystar body lift, was used to assemble a jeep, then guy parted out his jeep


7-27-2013

pulled both front axle shafts, hubs, steering knuckles and tie rod arms off the Cherokee then hauled it off to scrap today, on way home stopped at a yard sale and picked up a nice timing lite for 5 bucks, my father dropped off his explorer yesterday, will be pulling the 8.8 out of it soon


8-13-2013

made some more progress on the floors, my wife surprised me with a brand new runva 12500 lb. winch, just have to get a winch plate for it now, looks like I need to kick it in high gear and get the jeep together so I can use it


9-26-2013

have made a lot of progress on it, will post a few pics soon


11-16-2013

11-30-2013



some more floor work, picked up a new winch plate last week for the jeep too, hoping to order a sye kit after xmas


1-12-2014

got a bit more work done on the jeep, we had some bad weather and ice storms for a bit, coldest it got was -49 with the windchill, finally warmed up this weekend to get a little work done again, until my welding helmet died on me, took some pics will upload when i get some time


1-26-2014





started boat siding the rockers and doing some more floor work, got a huge dropping of snow last night too


2-2-2014

picked up a 4wd 727 auto from a 86 dodge 1/2 ton, was bolted to a 360, should work great for the jeep, i kept the shifter, cable and bracket form the parts cherokee so i think i can make the cable shifter work on the 727, still have to get the sye kit for the transfer case and im gonna see about getting a 6 pinion planetary and a wider chain for the 231, i already have a front shaft from a cherokee so i will just have to get it shortened once its all together


3-1-2014

more boat siding today,should have my camera back next week for some progress pics


3-9-2014


patch i made on the passenger rear side



started making peices to filll in the holes from the boat siding on the passenger side



drivers side rocker panel, i think it turned out okay



still have to weld every thing up and grind it down



4-27-2014

had to take the last 6 weeks off from the jeep, only four of those were due to medical reasons, but im back too work tomorrow and back to the jeep build as well, i do have a few progress pics that i never put up either that i forgot about t


i can still remember when it looked like this


4-28-2014

i had this piece welded up before, didnt get any welding done today but i did get a couple small pieces made up for it



4-30-2014

no work on the jeep tonight, but the last 2 nights i made some good progress on it, tonight i put a new rf wheel bearing and an engine belt on my brothers 03 liberty


5-19-2014

been pretty busy around here lately, have made some progress here n there, bought some thing for the jeep, its a gonna be a surprise for later for anyone still following this build, no pics of anything yet unfortunately


6-8-2014

so i haven't gotten very much work done on the body, other then putting primer on the spots i have repaired so far and i sat the body on the frame for now, had to get the chassis out of the drive way for now, having a bbq soon for my dads retirement party



body is just sitting on the mounts for now, gonna pull the 4cyl out and start mocking up the new mounts for the 360 



picked up a dana 44 from an 84 dodge, has the one piece axle shaft and auto locking hubs





machined the rotors for now when i was at work, disassembled the hubs and cleaned and repacked everything, have to get new seals, ball joints, tie rods, u joints for it, im not gonna worry about getting new brakes until its at the point of being drive able, i think my brother in law still has a couple of 9" rear ends, if so i will be getting one for the rear, if not i will get what ever i can find, i have all the stock axles and drive line parts up for sale, so hopefully i can get some cash out of that for some new parts, since the new front axle is passenger drop i was thinking of getting a dana 300 with twin sticks for it


i also picked up a cb radio and a 20ft chain all for 8 bucks at a yard sale


6-19-2014

as it currently sits with out wheels again, at least its inside this time



sold the stock front and rear diffs, front dana 44 is some what in place for now, i will have to out board the springs before it will be properly in place, talked to my brother in law kevin and he has a 9inch ford rear end for me, i may have found a passenger drop transfer case for the jeep, hoping to sell some more stock parts so i can keep getting more stuff for the jeep


6-21-2014

definitely lots of rust up here, lol, it seems like i work on it in short bursts, it try to find time for it but other projects come up first, i'm trying to sell some of the unneeded stock parts so i can buy some of the little things like front end parts, brakes and gaskets for the engine, they are what seem to eat up the most money


6-23-2014

made a little progress after work today, started on some seat brackets, the mounting points on the cherokee seats im gonna use arnt as wide so im making a few brackets out of some 1/4 steel




and dont forget to measure twice and drill once, i may have forgotten that on one


6-28-2014

picked up a 9'' for the rear, dana 300 with twin sticks and a cj hood, will have pics soon





6-30-2014

picked up some 15x8 rims from my father in law, they are older chrome rims from his old ford pickup, gonna sand them down and paint em black, i pulled a tree stump out of the back yard today too, i looked in the garage and thought to myself, i really need to clean this place up


7-1-2014

thank you, progress has been slow, but i have lots of parts to keep me busy for a while now


just a pic of the trans transfercase together

i just talked to my brother in law and he has another centre section for a 9 inch and another set of gears for a front dana 44, so i may be regearing the axles soon


7-27-2014

new to me cj grill, wider front fender flares and a pair of front fenders





i also made a scrap run yesterday to clean out the garage and get rid of any parts i cant use or didnt sell to make some more room in the garage again


8-16-2014

got both my front seats mounted up today, will get some pics when i have time



new seats, they are out a cherokee, i had to make some brackets for them to work with the yj seat mounts



new dash, i had to cut out the hole for the steering column and the defrost vents


8-24-2012

Got the 9" in the rear today, cut the perches off and moved them inward, haven't welded anything yet, found out that the spider gears are welded solid or there's a locker hiding inside of it, I have to pull the center section out anyways to swap in another one with matching gears for the front so I will know more when I do


9-12-2014

I haven't made much progress lately on the jeep, I did put a new roof on the garage, tore out a bench that was way too big and replaced it with some shelving, and spent the last 2 weeks after work trying to get the garage cleaned up and the jeep cleaned out. It seems that in between working on the jeep it gets filled up with all sorts of random things. I did however pull the 4cyl engine/tranny out for the last time today, now that its out I can work on the front suspensionand get the front diff installed. Unfortunately I probably won't make it back out there till next month with Xmas in a few days, but I have lots of parts to keep me motivated and moving forward,

I hope everyone who is following along has a merry Christmas and a happy new year


1-5-2015

I managed to get the drivers side arm off the knuckle, pulled the studs out and cleaned up the rust, gonna paint it tonight, my cousin has my passenger side knuckle and is gonna see if he can machine it for me at his work


1-11-2015

ive been working on out boarding the front springs lately, came in to take a break from the cold, i have the drivers side mounts cut off and every thing ground down, i started making my brackets to move everything outwards, i will post some pics later when i call it quits for the day








mounts are only tacked together until everything is in its proper place, everything will be reinforced and beefed up and a pic of the new shelves i made to get ride of the huge useless bench


1-31-2015

made some progress lately, not alot , but some



filled in the tube and ground it flush




some more pics of the rear bracket, im going to drill threw the frame and sleve it 



getting it ready to drill


4-5-2015

Got a little more work done on the jeep this weekend, haven't been out in the garage much this winter, will have some pics up once I get some more work done again, gonna try and get out there at least once a week from now on, the wife may be getting her father's old Camero, its a 78 with a 350 auto in it, its been sitting the better part of 15 yrs in storage, so may be doing some work to it to get it on the road for summer, also just ordered some new turkey calls and some camo for the spring turkey hunt coming up


4-13-2015


rear spring bracket in place, still not fully welded and i still have to sleve it



i did get the passenger side spring mounts cut off and both of the engine mounts cut off, every thing is ground down and cleaned up



drivers side tacked in place until i get the passenger side done and make sure everything is in its proper place before final welding



i have a small shed on the back of the garage, were gonna tear it down and re build it, this is some of the wood and the door for it, all the wood came from my father in laws farm



free 1 ton chain hoist i was given from my father in law as well



this is an old hand operated well pump i just picked up too, it was actually made about 20 minutes from the town i live in now, its gonna go in our garden this summer


6-13-2015

Managed to find some time here n there between turkey hunting and work to get a bit of progress on the jeep. The front suspension is all tacked together and the front axle is sitting under it, I'm waiting on new u bolts and plates for the front and rear axles, should be getting new ball joints for it soon too, once it's sitting on all 4 wheels again I can start too mock up the motor mounts and finally get the 360 in it. I also managed to pick up an old 1979 Honda atc 110 at an online auction, it doesn't run but the engine isn't seized so if I can get it running for cheap I may keep it


6-22-2015

i have all the new u bolts for it, my neighbor cut me 4 new plates for the u-bolts, i just have to drill them, i already started on two of them. i also got my steering knuckle back from my cousin, he was unable to do anything with it, problems with machines at his work, i gave both steeringknuckles to my neighbor and he is going to machine it down and drill/tap it for me, he also says he can make me both steering arms for, big bonus there, he will be getting some beer for that, once i have them back i will order the ball joints and it will be rolling again


6-27-2015

i was able to get all the new u bolts and plates installed




these are the plates i made, i cut the ends and bent them up and then welded across them




i did get all 4 of them made, i just didnt think i needed pics of them all



thats all for now


8-1-2015

i wasn't able to go with my neighbor today, but he was able to machine my passenger side steering knuckle for me




i took the tail housing off the 727 yesterday, im going to cut it down at work to shorten it and my neighbor is going to weld it back together for me



the next few pics arnt the greatest but i have the frame sleeving almost done





i picked up a few of these little led lights im going to use on my dash for different things 





i still have to pick up the new ball joints before i can put them on and i still have to make the high steer arms but things are still slowly moving forward


8-11-2015

was away this weekend, went rafting down the Ottawa river, on the way up we stopped at a yard sale and i picked up a muffler for 5 bucks and a compass for hiking and my wife bought some plates



10-2-2015

rear housing has been shortened and a new plate welded on




picked up some new ball joints for the dana 44, if i have enough time this weekend it may get put back together



10-14-2015

The drivers side of the 44 is all together again and the jeep is sitting on 3 wheels, won't be long till its a roller again


10-20-2015

Passenger side of the 44 is almost back together, just have to clean out the caliper mount threads on the spindle, bolts were getting pretty tight so I figured they could wait one more day


10-25-2015

pics aren't the greatest, but its rolling on all 4 wheels again




11-21-2015



hard top, doors and windshield are back on. I will be bringing the engine home from work next week, if i can get the engine and transmission mounts ordered that I will be using then it will have an almost complete drive train mocked up.


1-17-2016

Went outside to do some work on the jeep, I removed the old skid plate and wanted to start mocking up a new skid plate/cross member for it. Problem is that the angle iron i wanted to use on the two side rails for it are only 1 1/2" wide and I need 2 1/2" wide pieces. So now i have to buy 2 pieces for it which is no big deal, i just wasn't able to do what i wanted today. I was able to dig out my transfer case and load it up into the explorer to take to work tomorrow, i'm going to swap the rear output yoke with the double cardon yoke I stole off of a parts transfer case and re-seal 2 of the covers on it that are leaking a bit

I also did some research on my 9" rear end, it has the 2 ribs and an 'n' in the center section which means it should have the 31 spline shafts and the bigger bearings in it, also may have a locker in it, I'm still skeptical on the locker though, axle came out of an old farm truck so its possible the spider gears were welded at some point, not a big deal if they are, I have 2 spare centre sections and one of them has the matching gears for the front axle I have. Just need to pull it all apart some time and see what's in there


1-18-2016

re-sealed the 2 covers on the dana 300 today at work


1-23-2016

engine and transmission mounts are ordered and will be here monday


1-24-2016

Pulled the 9" out of the rear and cut the shock mounts off of it. The mounts were in the way of the axle sitting centered under the jeep. Rolled it back under and centered it. Started going threw my boxes and containers of parts and bolts, found my flex plate bolts, starter bolts, starter and flex plate shield to get the engine/trans bolted together for when it goes in the jeep. Found out that my flex plate is wrong for the transmission I have. Mine measures 11 1/4" and I need a 10" one. Hopefully I can find one soon


1-25-2016






from what I have read online the double rib and the "N" stamp means it should have the big bearings and 31 spline shafts, no idea until I open it up



I also found the right flex plate i need, a friend of mine had one sitting in his garage


1-31-2016

Did a few little things today in the garage, cleaned up my work bench and found the studs and nuts that go in the transfer case that bolt it to the transmission. Found a few more containers of nuts and bolts. Found my tool for priming the oil system. Didn't get a chance to pick up my mounts, will hopefully get them this week.

I have two different air cleaners for the engine, one came off the 360, one came off a 318, the one from the 318 has the valve system on it for letting in hot air from the exhaust manifold shields on a cold startup. I have a couple different exhaust manifolds and can't remember if they still have the hot air shielding on them, if they do I will see if I can make it all work.

So maybe in the next few weeks if the weather isn't bad I may have the drive train finally set in place.


2-7-2016



engine mounts


2-27-2016

Bought some metal today to hopefully work on making the trans cross member and engine frame mounts tomorrow


2-28-2016

Have the trans crossmember mocked up, no pictures because the batteries were dead in the camera. I also installed the new mounts on the engine and started figuring out what I need to do for the frame mounts


4-24-2016

here are some pics so far







When i first mocked up the transmission crossmember I was going to use the one I took off my brothers cherokee, but it was still to tall so i'm making one using the ram charger isolators I bought when i ordered the engine mounts, after looking over where I placed the engine I may cut off the mounts and move them back an inch, since i'm using the CJ front clip i'm going to need all the extra room I can get


4-30-2016

Today I put the CJ front clip on the jeep. I wanted to see if the engine was going to have to be moved farther back or not. I still have to put the rad in and the fan on the engine before I will know




You can see where I am going to have to modify the fenders for the boat siding I did on the rocker panels






5-9-2016

Checked clearance between the rad and engine, I originally had the rad bolted outside of the grill, I'm going to have to trim the brackets off of it and mount it in the grill instead, will post up some pics once I get back to it


5-27-2016

Thanks, progress slowed down because of Turkey season, but that shouldn't be an issue now, my next step is to figure out what I'm doing for a rad then see if I need to move the engine back a bit more or not


7-20-2016

Moved the engine back 2 more inches, needed the fan to rad clearance

forumrunner_20160720_063507.jpg

Also Installed the steering box and modified the cj grill to fit

forumrunner_20160720_063454.jpg


8-5-2016

Haven't worked in the Jeep lately but I think I'm gonna hit up the pic n pull and see what I can find for a fuel injection set up with the harness/computer system and all the pulleys and brackets


8-22-2016

Spent some time at the wrecking yard to see what they had, I was already there getting a door for a friends car. Thought I found the perfect truck but it turned out to be a 5.2 and not the 5.9. I've been looking on Kijiji at vans and trucks, seen a few but nothing close enough to me


11-27-2016

Bought another dash and a rad for it, the jeep is taking a time out for a while, will still be collecting parts for it. We have a new edition to the family and a my wife got her dream car from her dad. So the Camaro is going to be first on the list of things to do


1-29-2017

No progress on the car or jeep, but the other day at work I put a 2 1/2 skyjacker lift kit on one of our parts guy's jeep, it was a 2013 wrangler


4-22-2017

Sold the original engine today and used the jeep as a work bench


7-3-2017

I have my pieces for my transmission crossmember at work and I loaded up some hardware for it into the car tonight. Hopefully gonna at least tac weld some of it together tomorrow


7-19-2017




7-21-2017



A little more welding done today. Got the 2 inner end peices in place


7-23-2017

I cleaned up about a 1" area around the area I needed to weld. Will clean the whole thing up before I paint it. My phone takes horrible pics
