just bought rr supercharged 2007. at 85 miles n odometer started a loud knocking noise near front drivers area only when going over bumps. any thought on the cause???????????????

 

Not a clue, have you been in touch with your dealer?

On the 06 and 07 supercharged, there is a vent in the front right wheel well that often touches the wheels over bumps, dips, etc. This much more of aproblem with larger diameter after-market wheels. (the 20" stock SC wheels do this). Anyway, just a thought.

Yes, I know it sounds like its coming from the left side, but you are on the drivers side, inside the car, trying to listen to the noise right? Best bet is
1. Have someone stand outside and listen while you go over a bump.
2. Check that stupid vent in the right wheel well to see if it has scuff marks.
Hope this helps.

 

loose swaybar
tightened by tech
no sound

 

Good stuff!-- that is that you got it fixed.
bad that it was loose in a brand new car.
