has anyone ever had any drivetrain problems where they had to change drivetrain bushings or any such thing. im getting a very harsh ride in the rear of my car i replaced rear shocks and springs car is a 2006 s type with 41 k on odb. and im still getting a very harsh ride the rear just drops with a clunck going over slightest bump, also sometimes i hear a cluncking sound in rear of car like something was loose i first thought it was the spare but its not and there is nothing rolling around in back please help with and info before i go to dealer

 

Your car may still be under factory warranty. Get it in to a dealer asap.

 

I have attached a TSB that might help. It does end at the 2004 year but not all problems are fixed in the year the factory says they are! I am surprised your changing bushings at 41K miles? My 2005 STR is at 48K miles and everything is tight and quiet??

I already have the insert placed in my diff bushing but the clunck it's continuing
When we will have time we will inspect the drivetrain and go to upgraded bushings
I think we will custom made them in our garage
