Squirmy rear eand
I have Nitto mudders on the jeep. It 'feels' to me like when first moving forward, that the rear is squirming. It's like a low tire pressure (checked - not it_ or loose wheel nuts. (checked that too.) I can only feel it when first starting to move for say 20 feet, then goes away. Just a strange feeling. Any ideas??

Are you lifted ?

Sway bar/links in good shape ? Track bar raised for roll center correction ?

Are the tires new? Did it start right after the new tires were put on? You may have crooked treads on one tire. You are either going to have to drive slow and have somebody watch the rear tire treads or jack up the rear put it in neutral and turn tire. See if the treads run straight or if they wiggle like a snake. The squirming you feel may be the new treads grabbing the road as you go slow and as you speed up the treads loose their grip so it goes away.

the vibration? thats normal. my 37 grapplers do that too.

I can feel every lug when I am rolling at idle

EDIT: What I'm describing is clearly not the same as the OP's issue. I'm just thinking out loud regarding a squirming rear.


My rear squirms too. I have 33" and a pieced together maybe 1.5"-2" lift. The rear feels like its 'kicking out' to the side over many bumps, but not all. Trackbar is murderously torqued so I know that isn't the problem.

I don't think its the wheels or tires because they were on my wife's jeep for a week when originally bought and her jeep felt fine (stock suspension).

I will recheck torque on sway bar links I guess. My other theory is control arm binding or torque.

OP, keep us updated.

You guys have raised track bar brackets ?

I have an adj track bar, no bracket. Don't want to hijack the OP thread too much though.
