Suspension feels like rumble strips; WHY
 

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 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:
Kurt
