Finally fixed my wandering problem!!!

So I bought my wj nov of 2011. It developed a wander and also would pull to the right when I let off the gas and pull to the left when I accelerated on the freeway. I started by replacing the rear upper ball joint and upper control arm bushings, both genuine mopar parts, also added 2" bds coils and shocks. Wander was still there and so was the gas pedal steering issue. New addcos is front and rear, still there. I replaced all other control arm bushings and control arms I had made to stock spec by ironman fab. Also tried jks Trac bar as I saw movement in the Track bar. Didn't help, sold jks Track bar, and the bds coils and shocks. Lowered my jeep back to stock. Added goodyear duratracs. Problem definitely improved but still it needed constant correcting on the freeway. I messed with the steering box and determined it was bad after a few attempts. Wow way better ride! Still had a slight rear end wag! So I went through susp stuff again, tres good, all control arms were good except the rear uppers completely torn through. Replaced them today and man I must say I now officially love to drive my wj! I actually like it stock with the 245-75-16 duratracs. It ride primo now! The bds coils gave me 3" not 2". And I believe the first time I did the rear a arm i tightened the bolts before the jeep was on the ground hence why they tore. They were torn completely through. Ball joint was still good. Replaced them with dorman bushings, only 10 bucks a bushing instead of 50 and they seems great quality. Also I ordered prothane poly bushings for the front and rear end links and I am going to try the rear Tj track bar bushings for my trackbar. Prob weld washers on the mounts be abuse they are slightly wallowed. I'm so f$&^ing happy that my jeep drives straight and true now! YES!

After I adjusted steering box and it was still bad I replaced it with a duralast, that definitely helped. My iPhone cut that part out and I accidentally hi send, I'm on the mobile app so I can't correct, so if there is mis spelling I'm sorry

I'm having the same on gas-off gas wander. So, the steering box adjustment did not help, but replacing the steering box with a duralast brand steering box helped? and then I should also look at the control arm bushings to see if any have torn through?

I'm kind of a noob, but it sounds like the same symptom. I'd like to start with addressing the items that have successfully relieved the symptoms for someone else.

First thing to check is the bushing in the rear LCA's. On mine the bushing had come loose from the steel sleeve that the bolt goes through, and it would pull one way when on the throttle, and the other way if you led off the throttle

Okay I crawled underneath, and I'm unable to see any bushings that are obviously failing. Yet, I have the 'directional change' symptom when transitioning on-off the accelerator pedal.

Would it be obvious?
Is there a recommended testing method to evaluate the bushings?
Are there other bushings that I should look for too?

I'm unsure that the steering would cause this, it seems pretty tight at both high and low speeds, but I'm no expert.

(You know, at first I thought the lug nits had come loose on a wheel. That's how it behaves.)

Thanks,
Greg(Lovat)

Did you take a prybar with you under there? Get a good look at the bushings. Use the prybar to flex the bushing mount location in the UCA. Also, check this while the vehicle is at rest height. Wheels on the ground. Pry the UCA down and the bushing should show obvious signs of deterioration. Check both sides. If your WJ is doing the gas on/ gas off wander, it is most likely the bushings in any of the control arms. Upper or Lower, more likely upper.

When you replace the bushings or the UCA/ bushings as an assembly make sure to replace the ball joint on top of the differential. No need to go in there and do the same labor all over again.

My Dorman a-arm bushing's (via IRO) are too soft. It temporarily fixed my wandering but now it's back. 2 months later. I'm going to have to pony up for some MOPAR bushings instead of this Chicom junk.

throttle wander

If I can put my opinion forward. If its wandering on/off throttle then my bet is on lower control arm busings. A way to check this is put the handbrake on and in park. and get someone to rock the jeep back and forward. You will see the bush deform as the jeep is rocked back and forth. The reason I say lower arm bushings is because they have the job of keeping the axle square. If one moves more than the other, then your wheelbase will change on and off the throttle. The upper a arm only keeps the axle from twisting.

I filled the cavities in the lower control arms nvh bush with sikaflex 249 ( i think that was what it was called. Its the one they use on windscreens to stick them in) and that fixed the problem 95% I now have to do the uppers and I should be good.

Going through this myself for the last while. Got the back all rebuilt and running properly now, but can feel the front a lot more. Trackbar seems ok, but I know the LCA on drivers side is in rough shape. Waiting for my new lowers to come in. I'm thinking there may be an issue with steering box as it just doesn't feel right. We'll see once I get the LCA's and get them in. Replaced the uppers with RE adjustables. Up to about 80km feels pretty good, and made a huge difference (same deal with them) but over not so good, and when braking 90km or over it feels like I have warped rotors (which I don't) and think it's due to the LCA's. Just not enjoy driving this thing like this, and all the stupid *** little problems I'm having to be dealing with the last several months. Hoping I an get them all tracked down and fixed. This is the biggest issue though.

I would be surprised if that sikaflex 249 lasted long. All the twisting that is going to happen in the bushing. It is better as a sealant.

Thanks --
The duration of that sikaflex fix was a question I had. I'd be willing to hear more on that fix, to see if it is a temp fix or permanent fix....
right now, I'm leaning tword new LCA's it has the advantage of being an easier repair, for not much more money.

Yeah that stuff is used for joints in concrete and the like. Not really intended for situations where a constant flexing will be taking place. I have seen it eve fail shortly after being installed in a concrete joint...lol
