Excess body roll usually means the links on the rear sway bar have parted company with the car. They have a viton insert that holds the bolt on, and when it goes bad, the link will fly off. MB sedans do NOT roll -- to the point, on the W115/4 chassis, you can push a tire off the rim under hard cornering!

Check the bushings on the swaybars (fornt are rear) as well. Check to make sure the sway bar end isn't broken off up front, this is a fairly common failure at high milage.

Bilsteins usually start to knock pretty badly when worn out -- the compensating piston (under nitrogen pressure) that keeps the oil compressed (and air out of the shock) will eventually hit the shock piston as it rises as the oil gradually leaks out. When they start to crash on bumps, replace. Usually no other symptoms.

New one will ride better than ones with 160,000+ miles, though....
