Mercedes-Benz CL500 Tandem Hydraulic Pumps May Leak From Either Section

(7 reports)

Some models have tandem hydraulic pumps—one section for power steering and the other for suspension adjustment. These pumps are prone to leakage from either section.

Had hydraulic pump changed several months ago due to rear left wheel base falling below driveable condition. Repalced pump Sovlved problem for 3 month at which point I stated to hear a rumble come from under side of car that could only be heard from inside the cabin. I initially feared transmission but within a day of noice starting I Noticed the left rear begin fall again. When I took it back to mechanic he informed me that the hydraulic pump had gone bad and replaced it under warranty, in additionhe also changed The Resovoir filters which were clogged. Unfortuantely the noise under car has not subsided and after a week of use the rear left has begun to fall again. Is there any special procedures that have to be considered when replacing pump & filters ? -
