Still need help!

Ok guys im back with the same vibration as my earlier post. I pulled the rear end from the car and took it about thinking it was bent axles. Replaced both axles,seals,bearings. also replaced pinion bearing,seal,crush collar, and nut.Got the preload i need on the pinion so its good there. My problem is the vibration is still there. It gets worse with speed. Could this be the driveshaft is out of wack? i have been running theses 4.10s for about 2 years with 0 problems. If it was the shaft shouldnt it have started earlier on? Would it be a good idea for me to get an aluminium unit? just need some help here. thanks

U joints? That you be my first check. Very cheap fix.

Tires? I've had a bad tire make a decent vibration on the road.

I just changed the u joints, and my tires are new. Maybe a bent rim? But the vibration sure feels like a driveshaft. Kind of feels like my old Dodge truck i had that had a bent in the shaft.

I chased a bad vibration in my 02 gt for a while. I had my tires balanced 3 times and it still had a vibration. 4th time I went to a different shop and he hooked it up to the roadforce and it got better but was still there. I then replaced my shocks and vibration was gone. Shocks were blown.

May need your driveshaft balanced?

 

[jlds91389]

thats what it feels like but why would it just start?

May have been when you changed the u joints..

Does your car have adjustable rear control arms? If so, it sounds like the pinion angle is off.

nope rear control arms are stock but i did find the problem. I had two bent axles and my companion flange was a little warped. I put everything back together and rotated my driveshaft 180 jsut to see took out almost all the vibrations. Maybe a new driveshaft will take it all out

A good enough excuse to get an aluminum driveshaft to me!!
