You wanna go forward and back. use the method I described. The differential needs to want to rotate so you can see the action of the bushings.

One thing at a time grasshopper. Make sure all the bushings are good, then we'll talk about ball joints and unit bearings.

Flat ground, engine off, put it in first gear, emergency brake off.
Crawl underneath, and rock it front and back.
Watch the action at the joints where the control arms attach to the frame and differentials.

Any of the bushings worn....

I have no idea. Could be any number of things.

Have someone push/release the clutch, while you crawl under there and look/listen. That's where I'd start.

Still thinking the u-joint thing was correct....similair issue/ noises a couple years back...had them replaced 2x before they got it right...been good every since.

I bought a Firestone Lifetime Alignment. I get free alignments now. For the initial investment of ~$120 (cost of 2 alignments), I've had over 10 alignments in the past few years, i've actually lost count....but I sure as hell have been able to dial in my steering and suspension very well.

what do you consider "a little low" with 32s?

He's at 4.4°. I've driven at 4.4° caster and it was squirrely as all hell, there was tire shimmy, little return to center on the steering, dartish and it followed every rut or imperfection in the road.

Also every time I hit a bump or turn I can feel the jeep bounce from left to right.

Whenever I engage the clutch to shift especially at low speed turns, it feels like my tranny is knocking around done there, some metal to metal noise >

Actually, I think the PO bought cheap parts, didn't have a grasp of geometry and as such did NOT get an alignment after the lift was completed - notice in the pic above, the toe-in was all screwed up when he went to the shop. The PO never got an alignment after lift install. The Jeep drove like absolute crap compared to before, and the PO didn't understand, so he dumped it off onto the next sucker.

Sdavidf Just a side note since sway bars don't affect DW. But while the stock position for the TJ sway par is near parallel, I have heard from a company that makes sway bars that the optimal operation is for it to be 5 degrees above parallel. Seems that is about where yours is.

A stock pitman arm will fix the bump steer you don't even know you have, not the DW or caster issues.

I don't know if your shocks are too long or not. The brake lines appear to be stock, which means when you drop the axle and turn the wheel, the brake line acts as a travel limiter....until it rips off. But again, this is all stuff that should have been checked when installing the lift.

Most people don't even know what to look for in terms of suspension mechanics and what works/what doesn't. That is painfully apparent by the installation of the drop pitman arm, which actually makes the drive-ability significantly worse than stock.

You didn't answer my question. Did you have the tires ROAD FORCE BALANCED?

Also, what were the exact alignment specs? They should have given you a printout. What was caster, camber, toe-in, etc?

for the last time, the sway bar has nothing to do with your DW.

and that could be a problem. How much lift do you have? Have you checked the bushings (upper and lowers)? ball joints? unit bearings? tie-rod ends? post more pictures of your steering, taken to capture the inside of both tires...it looks like you may have a drop pitman arm, which is a whole different problem in itself.

EDIT: After looking at another wrangler in my parking lot, all of my control arms appear to be stock :/ the last picture i posted is just so if anybody knows if anything looks "odd"

Rolf Drag link looks fine.

It is hard to tell what the angle of the sway bar is from the photos. What I can tell you is that the links are not the fatory links and might be too long. Like UnlimitedLJ04 said though is that they will not be the cause of DW. You can remove the swaybar and should still not get DW.

Not sure if you are infact experiencing DW but check your upper and lower control arm bushes and torque.
11-12-2012 07:15 AM
Lotek Sorry for the double post but I also saw this gap on my drag link and wasn't sure if it was normal :/
