Default Vibration after rearend install

I bought a used s60 last fall and have had a horrible vibration ever since. I have changed driveshafts, changed axles, changed ring and pinion, balanced the tires, adjusted my pinion and and control arms, aligned it. Everything I can possibly think of and still get a vibration. Is there anything else I can try to solve my problem?

Thanks, mike

Mike have you pulled the axles to take to a local machine shop to check runout? I would have them put them on the lathe and put a dial indicator on it to make sure you don't have a bent axle.

are you 100% sure you have the right length driveshaft?

Balanced the driveshaft?

Have you put the rear in the air and ran it?

Yes and yes. I was told the torque converter could do it too. It does it the worst above 60 in overdrive but in 3rd it isn't bad until about 80mph

I know you said you replaced the driveshaft, but did you check the u-joints or replace them? U-joints usually vibrate more at cruise speed or upon deceleration.

did you change the trans mount at all when you did this? Usually the Poly mounts are different heigh then the factory one and will cause one hell of a vibration.
