Rear wheel wobble

other than being off balance is there anything else that would make the rear drivers side wheel wobble? I had nasty death wobble so I had all my tires balanced and my front end aligned. Solved the problem. When I'm driving now, if I look out the window at the rear tire it's got a back and forth wobble to it, is it still off balance or can something else be contributing? 32" BFG km2's, 2006 TJ.

Could be......Bent wheel, bent axle shaft, or defective tire.

A good alignment shop should have caught a defective tire or bent wheel when they aligned and ballanced them. A bent axle maybe not you'll have to put a dial indicator on the axle flange to find that.

Before you drive it anymore Double check the lugnuts to make sure their tight, actually I'd go ahead and pull the wheel look at it real close for crack,dings,damage if it looks okay and the mounting surface's look good and clean reinstall it making sure it's fully seated and the lug nuts are tightened evenly to specs.

Does the tire actually wobble i.e. you feel it or does it just "appear to" wobble? If it really is wobbling you would have a hell of a vibration.

If a wheel or axle is bent bad enough, the alignment machine's computer won't calibrate the sensor on that wheel. At least, that's how the Hunter machine I last used was...

Most likely it is one of these reasons. I had to replace my rear left rear axle because it had a wobble to it. The girl I bought the Jeep from said someone backed into her Jeep right before she decided to sell it. She thought everything was okay until I noticed the wobble.

If you use the rolling compensation feature it will but it will also show up on screen as a thrust angle issue. This is where a Good Alignment shop catch's problems and the in and out guys just take your money and shoot you out the door.

? I've been using a Hunter DSP600 for a long time and havent used other models so it's possible newer models may not have this feature?

it "appears" to wobble.

The thrust angle is off this I know. When the 2.5" lift was put on the track bar relocation bracket was never installed to re-center the axle, that's on the to-do list.

If it only appears visually and you do not feel anything, I would say it is not wobbling. Discoloration or changes in shading, or slight variation in the tread can make it look as if it is wobbling.

Centering of the axle is not going to cause a wobble or affect driving. A 2.5 lift is not going to move the axle much and you do not "have" to have the axle centered.

Here is an idea: swap wheels. Then observe where the problem moves or doesn't.

I'm having the same problem. I swapped tires, the wobble did not follow the tire so it is side specific. But what could it be. The guy who I had installed them used a super fine sand instead of weights. Brand new MT baja radial atz,s. 33/12.5/15.was worried that was it until I swapped them and it stayed on drivers side. Actually that would have been nice. So bent axle, warped drum or shot hub bearing? It's making 1/2 of the tire on the outer tread ring scrub the road and wear uneven.
