iv see people talk about death wobble up front, but what if u have it on the rear. when i drive down the road there is slight wobble at low speed but after i hit 50 the hole back of the jeep go's wild it clears up a bit when i hit over 60, and when i have a trailer on the back i cant go more than 45. what i have on my Cherokee is a add a leaf 2.5 and bfg at's.

 

i'd almost want to say bent rim or axle there are no real moving parts on the back

 

^^ x2. Or you threw your wheel weights and one of your tires is unbalanced.

 

had it at the tire shop wheels are balanced. that's what i was thinking, i have bent axle. know a good place to get some online. i have d35

 

Check the u_bolts.

 

I'd think about putting the rear end up on jack stands and spinning up the rear tires a bit to see what they are doing. Don't forget to put some blocks on the front wheels to keep them from going anywhere if the ground isn't perfectly flat. How old are the shocks? If they are worn enough they may not be controlling the tires anymore and the tires just basically bounce down the road with nothing to stop them.

 

U bolts, shocks, bent rim, etc. Start trouble shooting those 3 things.
