alright i just got new rims on my car, and when im cruising at like 58 or 59 mph and give it a little, the car vibrates a little bit then stops, so i had the tires rebalanced and everything, but then it still does it, they say the U-joint looks fine, so any other ideas on what that could be from?

 

driveshaft balance?

 

old rims had, or did not have vibration at 59 mph?

did you also get new tires?

if old tires, but new rims, did they put the left front tire back onto the left front? the right front back onto the right front and so on?

but, don't get yourself into what programmers call an unconditional loop. if it didn't do it prior to new rims, and does it after new rims, then it must be related to the new rims.

 

all new rims and tires, and had them rebalance them and everything, and after they fixed i didnt notice anything on the way to a place, but then on the way back it started again, so could it be that the lugs just need to be re-tightened like they have to be after they get put on?

 

I am having the same elusive issue, as are others, check out:

did it do it prior to the new rims and tires? That is the telling point.

Either you have an out of round rim/tire, it's not balanced correctly or something wa broken during the installation

too bad you can't slap on the old stuff.........can you?

 

i do have the old rims and tires sitting in my garage, i might have to give that a try

 

i have a similar issue and it think its the center section in the rearend. its getting worse as time passes so im thinking the slug is failing and letting the axles move on the inside causeing the shimmy. everything else has been replaced. motor, trans, driveshaft, tires a couple times, wheels a couple times, adjusted torque bar. once i can afford a 9in i will find out.
