a full 4 wheel alignment should include track bar adjustments, control arm length, as well as setting the front toe.

afterall they cant adjust the caster without control arm length changes.

I would offer to help, but I dont have the time this week.

go onto Jeepforum and research with caster angle is reccomended for a TJ with 35's, I guarantee the alignment shop doesnt know stock specs shouldnt be used. truly thats the only one really needs to be set. track bars center the wheels from Left to Right (if your off a little no big deal), toe should be between 1/16" to 1/8" inward.

the only concern is making sure they dont push the front axle forward when setting caster. if you do, the drag link will end up smacking into the axle side track bar mount when the wheel is turned all the way to the right.

as far as the rear axle is concerned, pinion angle is the only one that matters to within a degree. track bar length can be slightly off without much consequence. with the weight of the vehicle on the tires, measure fron the tire to the frame on both sides till it matches. pinion angle needs to have the pinion point directly at the output flange of the 241. the pinion angle and the driveshaft should be the same.

Ok Steve, gotta pick your brain some more Thanks by the way!

So lift is installed, everything is aligned, I realized I need an adjustable track bar in the rear now cause the axle is to far to the right. So the problem I'm having is this...

1. From start to about 30-35mph I get a bad vibration, over 35 is calms down.

2. While driving down the road, if I take it out of gear and coast...I get a grinding/whining noise...

I have not installed my Tom Woods CV driveshaft yet (they sent me the wrong one) and the rear driveshaft/axle angle isn't aligned yet (waiting for the new driveshaft to install it first)
Would all of what I'm describing be a result of the driveshaft and axle being to the right? Or should I start diagnosing and fixing something else in the meantime?

95% of what you said makes me think the stock rear DS is not operating at the correct angles. Which o would expect. Very simple to test. Pull the shaft and drive in 4wd and drive with your front axle. Nothing wrong with driving with just the front until the new rear TW shaft shows up.

Your grinding out if gear interests me though. I'm not good with manuals and clutches, but I would wait to dig into anything else until you get the rear shaft installed.

Good luck, post back up.

Thanks for the help Steve. It was the driveshaft causing the vibration and noises. I got an Adams 1350 shaft for it. Although, sadly after all the work I did to it, I like the way a 4 door feels and miss the extra room, so I'm going to sell it and get a 4door rubicon and build it up Yes, I do enjoy mod'ing jeeps lol.

Wheeling is much more fun than building the jeep. Whatever you end up with hope to see you on the trails.
