I decided that it would be best if the trackbar had a little bend in it. With some help from @Kyle M. we were able to put a bend in it and make it fit a lot better.

After putting the trackbar in, I rebuild the transfer case cross member and took out all the jack stands that were holding up the engine, tranny, and transfer case. After that, I was able to get the Jeep back on all fours for the first time since rebuilding the frame.

The steering column that came with the first jeep had all of the wires cut to a stub so they were completely useless. Other than that, everything else worked great. The steering column that came with the second jeep had all the wires but it collapsed in the accident and didnít turn well. Tonight we spent some time rebuilding the new one with parts from the old ones and now it works great.

Does anyone know of a place where I can buy some steering shaft parts for a reasonable price?

I guess itís time for an update. After getting the trackbar bent, we rolled the Jeep outside to clean up a little. Of course I had to get some pictures.

After some thinking, my dad decided to part with his XJ. My dad made a deal with me that if I continue to get a 4.0 GPA he will hand down most of his parts!! The parts from his drivetrain that I will get are his shaved 14b and welded kingpin 60 both with 5.38 gears. Iíll also be getting his 5.3, built 4l60e, and Atlas II.

I talked him into giving me coilovers as a part of the deal so now the air shocks will be moved to the rear with a 4 link. Leafs are for trees.

His axles have the 8 on 6.5 lug pattern so I am getting his tires and H2 wheels also.

After taking his Jeep to the scrap yard, we moved some stuff around with the amazing space we gained.

This is a few steps backwards but it is most definitely worth it and may even speed up the project since we know everything works great.

Not a whole ton of progress recently. Been spending all my Saturdays snowboarding up north. In the few days that we did work on the Jeep, we got a few things done.

We tore out the old drive train and began mocking up the new one

Went for the flat belly

Some sacrifices had to be made

https://uploads.tapatalk-cdn.com/201...5ecb917964.jpg

Made some motor mounts

https://uploads.tapatalk-cdn.com/201...61ed0e42dd.jpg

https://uploads.tapatalk-cdn.com/201...b97220b3e5.jpg

After we mounted it I just wasnít happy with how far the motor sat forward. The next weekend was spent moving it back 3 inches. We were also able to get the front axle rolled under the Jeep.

After getting the engine mounted, we moved the upper link to the passenger side and also frenched it into the frame to be able to have the bolt clear the transmission.

https://uploads.tapatalk-cdn.com/201...49f053f6b7.jpg

https://uploads.tapatalk-cdn.com/201...5a0cfed6ff.jpg

After that was done, we were able to bolt up the wheels with 37s for the first time. We also found ride height. Itís really low. Right now it will have about 4 or 5Ē of up travel but we could flip the tie rod and drag link to the underside of the knuckle to get at least 2 more.

Ride height (check out the flat drag link!):

Size reference. Iím 6í 1Ē

I got a tube frame steering box mount from Gtxracer on pirate or @duKeengineeringsolutions on Instagram. Itís a very cool and does a great job keeping the steering box up and out of the rocks. We had to cut the bumper off to make the steering box location work. With the front stretch, we will have to put the box out in front of the grill but I donít think it will stick out far enough to make a noticeable difference off-road.

After getting the link mounts all in place, we put in the shocks and the front end shot up since they had the springs for a Cherokee still on them (120 over 250). So my dad called up Accutune and after some measurements they had it all figured out and some new springs were on their way to us. They ran the numbers 3 times because of how light my jeep is. They thought there was something wrong with the math. Spring rates ended up being 100 over 120. I spend a couple nights last week welding up links and all the axle side mounts so yesterday we were able to get the front axle in and nothing will be redone again, no matter what.

Full droop

After the front end was at ride height, we balanced out the rear to see how low it would be.

Nice upgrades.

Glad to see you changed up the tcase and mounts. Solid mounting the motor and having the offset support on the old tcase, you would have been breaking adapter housings or transmission housings. Ask @firehawk :teehee: not :teehee:.

JeepHeap June 29th, 2019 09:35 AM

Weíve been working with the 4 link calculator trying to get this rear to work. This is the best one we came up with so far. The only issue that we can see with this one is the upper link is not flat, how critical is that? Any other thoughts or comments on these numbers would be greatly appreciated.

My only advice, don't worry too much about the numbers, I know I might get flamed for this, but I've read a lot about link numbers and setups, and look at many different combinations that all seem to contradict each other, and surprisingly they all seem to work just fine. I'd try to build it around what fits the best, keep your separations reasonable and you'll be happy.

I always appreciate seeing someone who obviously knows how it's done saying this. While I have never done one from scratch (only modified my junk), I have talked to a lot of people who have. They all say the same thing you did. Keep the basics clean and then worry about packaging....

Interesting story.... this past March we took 7 rigs to Utah. All different wheelbases and tire sizes. Everyone did fine. I tried this extreme V notch being spotted by Rich Klein. (founder of WEROCK). Extreme being that it was so narrow and steep that you could literally stand upright under my Jeep. I couldn't get my right rear tire to climb the side wall and ended up backing out. When I asked Rich his opinion, he said "you have too much understeer" and he explained the geometry issue. This made me sorta sad and feeling like my rig was sub par. That night I crawled under all the other rigs and couldn't see anything that was much different than my setup so I asked him about it the next day and what made mine different? His answer; "all of your rigs have under steer, you were just the only one to try that obstacle".

So what is under steer in a nutshell? Anyone with single triangulated rear suspension will have under steer. It requires a double triangulated suspension to correct it. After 11 years of wheeling my suspension, this was the only time that my "not by the numbers" suspension became an issue.

Take Kyle's advice. :thumb:

Not all of them worked just fine, some definitely work better than others. His numbers look fine. Only thing I'd try to do differently is keep the IC out around the front bumper. That being said, it'll work.

Fine for some is bad for others and what is acceptable is definitely subjective. But you understand what I'm saying and I know where you are coming from.

Thank you all for your input. Wednesday night we got to working on it and got all the mounts in and then Thursday we spent the morning getting all the links cut and assembled.

Once assembled, it was evident that the truss was going to limit up travel, so, the rear frame had to go. In its place is a tube section which is capable of 8 1/2Ē of up travel before the axle makes contact so it should be perfect for 7Ē of up travel.

The new rear frame rails will be into the body about 3.5Ē; however, the floor will be entirely custom so it wonít be a problem.

We got some good work done tonight. Started by welding in the rear frame rails and cutting the rear floor pan out so the body could be set down on the frame.

https://uploads.tapatalk-cdn.com/201...8395cd2f6c.jpg

After doing that, we propped up the frame so that it would get close to ride height. It ended up being around 1.5Ē below ride height and got the front close to the same. After that, we rolled it out on all fours.

Belly is at 17.5Ē and the bottom of the tub is at 22.5Ē. In comparison, my dads CJ7 on 33s has the bottom of the tub at 25Ē...

And of course I had to sit in it holding my steering wheel.

Late to the party, but agree with feva4u.

If you find that the rear hops to much when trying to push the front end up a rock face, opening up the frame side separation will help. But I expect it will work well.

JeepHeap August 17th, 2019 09:28 PM

After getting the Jeep to the roller state, I added a front and rear cross member to strengthen up the frame.

https://uploads.tapatalk-cdn.com/201...8738335ac5.jpg

Iím pretty proud of the welds that I put down on the cross members.

https://uploads.tapatalk-cdn.com/201...e5a60984fd.jpg

Once the cross members were in I began cutting out the floors in preparation for building the floors.

https://uploads.tapatalk-cdn.com/201...2c1009aa42.jpg

Then, on Friday my dad and I moved the tub off the frame and cleaned up around the edges of where I cut out the floors.

Then, today we mounted the rocker guards and began working on the skeleton for the floor. We started by putting in a spreader bar marking the floor so we could make sure that everything was square. And yes, the spreader bar is crooked so donít let that confuse you, the body is squared up.

https://uploads.tapatalk-cdn.com/201...4ec9d80774.jpg

After getting everything set up, we made the first sections of the skeleton.

https://uploads.tapatalk-cdn.com/201...95057647f3.jpg

Then before we ran out of time to work, we got one of the hoops that go over the transfer case in place and cut the metal for 2 more.

If you have room, add a metal strip on the inside of your tub where the riv nuts are. Make sure they're tied into the frame somehow. They don't look good after a couple trips otherwise.
