Well, I don't really post much, but i do lurk around. I have an issue that i just can't seem to fix. So i thought there might be someone out there who could help.

I have 2000 Audi A4 Quatrro 2.8

The car has annoying shake from 50 mph to 65mph, it is felt more in the seats than in the steering wheel. Which would make you think its coming from the rear....? hmmm

Well, this is everything i've done to try and fix this situation.....

1. Three sets of wheels and tires...each road force balance twice.
2. Rear Wheel bearings
3. All Four Axles
4. Rebuilt transfer case
5. Fluids....rear end,front diff,transfer case, and oh yes.....Transmission ( I would definatly recommend....they say its life time fluid and there insane!
6. New brake rotors, Pads, and Calipers!
7. Driver and Passenger tie rod ends
8. Two alignments

If anyone has any ideas...please let me know.Thanks for your help.....

 

What tires do you have on the car? Do you also have a readout of the road force variation and the rim runouts?

Also, check the rear diff mount for ecess play or a collapsed bushing.

 

engine mounts?

 

Thanks, I'll check those items and let you know what i find out.
