Bent axles/axle tubes?? Early this year I broke the 4.10s in my original 10 bolt and ended up buying a stock 3.23 10 bolt from an LS1 A4 car. I noticed a vibration issue show up but I wasn't 100% sure it was rear end related because I also did some other stuff to the car (rebuilt trans, bought a set of ZR1s from another member on here, replaced broken throwout bearing and clutch master/slave cyls).
I had both the rear wheels checked and double checked for balance, I was told they were perfect. I then swapped a known good pair of wheels onto the car but it still felt the same vibration.
The other day I had a friend following me and she noticed that the right rear wheel was visibly wobbling, so we swapped cars so I could watch the wheels myself and sure enough it was visibly wobbling, pretty bad too.
When I got home I jacked up the rear of the car into the air and let the wheels roll in first gear so I could get out and look up close. Turn outs BOTH sides are wobbling pretty badly but the passenger side more so.
I guess at this point I'm 99.9% sure it's something in the rear end but what are all the possible causes of this?
-brakes?
-suspension problem? (panhard, control arms)
-bent axles?
-bent axle tubes?
The rear end also has LCA relocation brackets welded on. Could those somehow be messing it up if they were installed incorrectly?
The person I bought the rear end said it was in a nitrous car that was pretty quick so I guess there was some power going through it.
Any thoughts?
