Default Acceleration vibration.

Ive recently come upon a vibration in the rearend after bending my RR wheel. I had the wheel straightened and that vibration went away, but a vibration still occurs when under acceleration at probably 40mph and up. Ive yet to do the new axle torque (car is a 00' with 77k miles)

possiblilties:
Axle torque?
Bent axle face?
rear end mounts?
rear gear? <--hope not.

Bent rear drive shafts. Got mine replaced, No more vibration @ revs. Get a Drive shaft spacer too before you damage your new ones, Usually happens because of shitty suspension and your S is too low without the spacers.

It might be, when i bought the car it came with Ksport coilovers and it was way to low so i raised it a good 2". I took a dial indicator to the drive shaft ends and was only seeing about .005" runout.

Is there a spec?

took apart the axles today, the Right axle showed some darkening in the axle bucket nothing to severe. On the other hand the LR had two pretty significant wear spots. I swapped the buckets and re greased the boots and its working perfectly again =) thanks S2ki!
