Previously posted this in the "Suspension" forum, but no one answers anything on that forum for some reason.

2000 A-6 2.7 Turbo:
Just had front suspension including new OEM upper and lower control arms, struts, and tie rod ends replaced. Also had front end alignment. Also 4 new tires.
Also replaced rear coils and shocks with OEM parts because one coil spring was broken on bottom.
Work was done by ASE mechanic trained on Audi's and VW's.

Problem: car handles great but every road feels like I am driving on rumble strips. I am not happy after spending thousands $
This was not there BEFORE the work was done.
What could be the possible cause since everything is new and was replaced with factory OEM parts

Thank you for any suggestions or input:

I would guess tires, even if they are new. Is it vibration or road noise? Maybe have the balance re-checked. These quattro systems are senstive to tread patterns. I went from oem Pirellis to Coopers for a short time, and they wore badly (cupping) and vibrated. Went back to good Pirellis and Contis and no problem since.

Thank you for the input.
I will take the tires to have them re-balanced at another dealer just to be sure.
The vibration becomes noticeable at 35 mph and becomes a dull drone at 45mph
It was also suggested that I have the alignment re-done but this time by a factory Audi dealer as these suspensions are tricky for a local tire shop and Audi does a special alignment, so that will come after the re-balancing.
Thank you again for your help

Could also be a bad CV joint. An inner or outer cv that is bad can sometimes cause the vibrations you're experiencing.
