Tink in rear over sharp bumps
 

I have an sound, kind of like a "tink" when I hit a sharp bump. I checked sway bor mounts and the torque is correct.

Could it be a sub frame mount? Any ideas?

Same thing in my 300E. It is only on the drivers side.

Mine too!
 

Sounds like the drivers side only.

Are you sure its rear axel related. Check the trunk for any loose objects, Jack, tools etc. Check the rear door assembly, and under the seat.
If you think it is axel, Check the bushings for wear, Check the parking brake assembly, springs in postition, Loose shoe etc. And check the shock for a tight fitting, or wear

The shocks are fairly new and the trink is about empty. I will check the parking brake assy.

My parking brake assembly is making that noise too. Also check your rear stabilizer links. That can make the same noise on bumps.
