W208 Squeaky back end!

[Crashman5cca]

My 2002 W208 has developed a squeaky back end. It sounds like a knocking shop bed as I drive along!
Smooth surface: fine, bumpy surface: squeak
Any ideas what is could be?
Cheers,

I have this too actualy

my car passed MOT other day so I think it could be either the exhaust flapping around or part of the bumper ?

Possibly the anti roll bar bushes?

I was thinking anti roll bar bushes. If I push down on the back end when the car is parked you can hear it squeaking away

Squirt them with WD40, the makers say it's safe on rubber.

Lower hub bush/bearing can cause this.
