Rear End Wobble


Recommended Posts

OK did some work on the rearend and now I have a wobble at even low speeds.

 

What I did.

1. Took off old DANA 35

2. Replaced it with a Explorer 88

 

What I knew I did wrong - it was dark and I was tired

 

1. The axle is off center - maybe a half inch (it was marked correctly but I must not have seen it)

2. The pinion angle is wrong - instead of being straight or a slight offset - I'm past straight and offset the other direction

 

Could these be my problems? Or could my axle be bad?

I don't think either of those would/could cause wobble. Sounds like either a bent rim, or a bent axle shaft.

 

Put the back end up on jack stands, and run it in low gear to see what's wobbling. Once you see which side (unless it's both), take off the tire and rim and run it again to see if the hub itself is wobbling or running true.

All right excellent advice.

 

I jacked the rear end up, started it up and put it in gear. It made a terrible noise and the drive side wheel wobbled a little. The rim was bent but it has been that way for several weeks. But the noise. Got under and listen and looked.

 

One of the retention rings on the u-joint came out and the cap was not seated correctly. That let the drive shaft move back and forth as it turned. Reseated the cap and put another retention ring on and the problem went away - all is fine
