Audi 2001 A8 L - Intermittent vibration while accelareting
Audi 2001 A8 L, car intermittently vibrates only when accelerated. All four wheels were balanced twice recently. Also recently replaced both front (left and right) axles, front brake rotors and pads.

Thanks for your response. I just got this car about 6 month ago from auction. Frankly, I'm not sure whether it has hubcentric rings or not. I'll check with my mechanic. All four rims are original, not bended. Though, one tire (out of 4) is from different manufacture (!). Vibration appears only under acceleration (at ~50-60 mi/h and above) and especially when driving uphill or downhill. It looks like vibration feels more on the passenger side (both front and back) and it seems to come from under the carriage.
Once again I really appreciate your help!

You won't need hubscentric rings if they are the original wheels, although the fact that one of the four wheels aren't original makes me wonder.....
I would have all four wheels put on a balancer, if they are all good, then have the tech put the wheels back on the car and have him drive it up to speed (ESP off) while on the rack and see which wheel is causing the problem.

Installed four new Michelin Primacy MXV4 tires. Car runs much smoother, but vibration still occasionally occurs It is less, but it exists. I recall my mechanic mentioning that one of my front upper control arms had damaged rubber. Could this cause such vibration?
Guys, I really appreciate all suggestions.
