what would cause tail wag

So my WJ like to "wag its tail" when driving if I let off the gas. From what I've read, it seems like it could be the rear LCRs, but just wanted to check with you guys first before I start replacing parts.

Could check tires for a twisted belt. Could be control arm bushings.

you are correct... i spent a lot of money chasing this issue.... check the oval bushings in the arms for the slightest bit of play while your helper rolls the jeep back and forward with the front tire

Control arm bushings (Front/Rear) and Rear a-arm busings and joint would be the first place I looked.

It's done this on three different sets of tires/wheels, but good suggestion.

Thanks, I'll give that a shot. I was looking at replacements on RockAuto, and they seem fairly cheap, but the shipping is pretty steep.

I'll check the a-arm bushings too, thanks!

If you find the UCA bushings to be bad, replace the UCA and bushings as an assembly and definitely install a new ball joint on top of the diff. No need to have to do it all over again.

x2 on the rear upper control arm bushings. Tail Wag is the exact way I described it, and new upper control arm bushings (and ball joint while it's out) took care of the issue for me.

I have the same issue. Step on the gas and the nose goes left, let off and it goes right. Sounds like a new A-arm or at least bushings and ball joint are in order. Maybe I should go with a spacer to match my lift?

I changed the LCA's a couple of days ago, and no more tail wag!

That's the drivers side, and the passanger side was even worse!

Looks like I need to get under the Jeep and pry side to side to see if the sleeves are detached from the rubber.

Are all those parts installed already and you continue to have the wag? If so, check the lower control arms. Look at worn bushings as well. Use a pry bar and see if the rubber in the bushing is torn or disconnected from the bolt sleeve.

Yes, all are only 2-3 months old. I'll check them out. I may order some LCA from IRO with Clevite bushings to get rid of those silly oval bushings. It's very frustrating.
