Report: Worn Sway Bar Link Joints Causing Knocking Over Bumps
Mercedes-Benz CLK550 Problem
The sway bar end link joints may wear and cause a knocking noise over bumps. Loose or warn links should be replaced to correct this type of noise.

I would hear a crunching sound going over speed bumps, they had to replace a strunt and a sway bar.
