I have a Knocking/Clunking sound when going over bumps in my 08 LTZ with 65kish miles on it. Its not really loud but definitely to hear either. Seems to be worse at slower speeds.....Any ideas on what it is? Would like to bring it to the shop with an idea. After I get this taken care of, its off to the dealership for the tranny...Sad

This week, at 61,000 miles, I eliminated the same problem in my 09 by replacing one of the links attached to the end of the rear sway bar.
The replacement part was built so much better than the original which came with the car.
$29.00 + tax
Less than 1 hour of work.

Could be anything in the suspension with a bushing, could also be a strut mount.

More often than not this ends up being swaybar endlinks.

Grab 'em and shake em around. If they move, they need to be replaced. If not, move along through the rest of the suspension.
