Hi Glenn,

The damping on the E class estate models with self leveling suspension is done by the gas spheres on the rear floorpan & not withing the rear struts.

If the rear of the car feels bouncy with no damping then you should have these replaced - they often fail with the rear struts so we generally replace the rear struts & spheres together as one job to prevent any future problems.

Do these units self bleed when shocks are fitted, and is it the power steering that powers them.

Hi Glenn,

The power steering pump is a tandem pump that does the steering & the suspension.

To bleed the system you should have the car on a flat bed ramp, then with the engine running you disconnect the linkage to the self leveling valve at the rear & move the lever up & down a few times to raise the suspension up & down. This then bleeds the system out after it has been opened.

Best regards, Paul
