Dude! I am so glad you posted this because in my mind, I cannot believe that anything other than the track bar, can cause such a violent wobble. I do believe all the other suspension( ball joints, tre, etc ) parts can lead to it. But the track bar had got to be the contributing factor to DW. So what I'm saying is, I would think if a track bar is set up and working properly, I should not have severe death wobble at 35mph. Just my thoughts. But with all that said, I have tried 2 RC track bars and is hard for me to believe both were bad. The only thing I might do is put my stock trackbar back on with new stock style bushings. I just don't know what else to do.

 

you might want to look into kevins off road hard kor super hard durometer bushings, they are the best for stubborn wj suspension. not sure if theyll fit the RC track bar, a different brand bar wont hurt to bad.(jks) might run you 200 with the bushing upgrade if they dont fit your trackbar, but hell try the old trackbar first, if im not mistaken, 3 inch lift is the cutoff before you even need to go adjustable anyway. keep me posted

 

Thanks! I will keep you updated

 

JMHO, but you should just use your old track bar with polyurathane bushings.

 

Thanks Dave! My plan is to put on the stocker and if it helps I will probably just order another adjustable from a different company

 

I haven't been on here much lately. It sucks to hear you are still having problems. Did you ever see if you had room to add some shims to lower control arm brackets to get more caster?

 

Man, looks like this is giving you a headache. I hope you don't mind me sharing a thought from another angle. This sounds just like what we used to call "4 wheel drive Hop" back in the 60's and 70's. Same symptoms, 4x4's of every make would get extreme DW at around 42-45 MPH. and every time we came up to that speed.


Even if everything in the steering and control were new there were other reasons that would cause this 4 wheel drive hop:


Staying in 4 wheel drive after getting on the pavement or transfer case not completely disengaging out of 4 wheel on the pavement.


Not unlocking one or both front hubs even though the transfer case was not in 4 wheel. (just the extra drag of the Diff and Drive lines would sometimes cause this. could a bad ring or Pinion bearing dragging cause this on our rigs because we can't unlock the hubs from the diff and drivelines ?)


Common major causes were a Front wheel bearing or brake shoes/pads dragging badly, or a bent or broken axle.


It was just a thought, considering we can't unlock the hubs on these.


I hope you can get it ironed out!

 

thanks xjmike. On our WJ's, there is no way to add castor unless we put adjustable lowers on them.

 

I really appreciate your input! I have never given that any thought at all. Definitely will keep this in mind!!

 

So after i got out the woods today from shooting, i came home and put on the stock track bar with 16 year old bushings on. No play what so ever. The New RC bar has about a 1/8 in. of play. how can 2 new trackbars have the same problem??? UGH! anyway, the steering is so much tighter and drives alot better. i got it up to 55mph and started to feel a little shake so i slowed down. The bushings on my stocker or worn so i didnt expect much at all. So now im thinking, should i put new bushing in the stock bar or just buy an adjustable from a different company. HMMMM...
i dont want to get too excited just yet because i want to drive it for a few days to see what happens

 

Nice man. Sounds like you've gone from 35 to 55mph and it's not as violent. That's good news. I just replaced the bushing in my stock track bar last weekend. It was a pain in the neck, but a very mild vibration I had on the highway is now gone. FWIW, if I had to do it again, I'd buy an aftermarket bar. But I had other priorities on the jeep at the time. Hope you get it straightened out.

 

Are you sure?

From what Dave said it sounds like the same setup as an XJ. Loosen that bolt add a few shims more caster.

 

i soooooo wish it was the same as my xj. but no, they dont. They set em at the factory. I sure do miss my xj more each day! HA!

 

i sure did brother! now, im not saying i wasnt scared to death with every bump i hit but yep, 55mph!! woo Hoo!! So glad you got yours fixed! they can be a pain to get out.

 

i need a favor from someone please! could someone take a pic of there axle end trackbar bracket. i need to compare the two.
i put the stock bar on and im getting zero play. unlike the adj bar that was moving about an 1/8th inch on axle side. but im still getting DW but not as bad as before. When i say"not as bad" i just mean i can at least predict when its about to happen.
