MERCEDES BENZ E-Klasse and predecessors Power steering pump replacement

The cost varies by year, engine size, and your location. Use the estimator above for an accurate breakdown of parts and labour specific to your MERCEDES BENZ E-Klasse and predecessors.

Common parts for this repair include: Power steering pump (hydraulic).

Power steering pump replacement on a MERCEDES BENZ E-Klasse and predecessors typically takes 2–5 hours of labour at a garage.

For a MERCEDES BENZ E-Klasse and predecessors, power steering pump replacement is typically needed power steering pumps are replaced on failure; typical lifespan is 100,000+ miles.

Power steering pump diagnosis should first rule out low fluid and a leaking hose — these are much cheaper fixes. Only after confirming the pump itself is faulty (whining that persists with correct fluid level, or confirmed low pressure on a gauge test) should replacement be recommended. A remanufactured pump for most MERCEDES BENZ models costs $80–$200; labour is 1–2 hours plus a system bleed. Confirm a full system bleed and test-drive is included in the quote — a pump that cavitates after replacement due to air in the system may be mistaken for another failure.

An independent is the correct choice for hydraulic power steering pump replacement on most MERCEDES BENZ models. The job requires no specialist software. Electric power steering (EPS) systems — now common on newer MERCEDES BENZ models — do not have a hydraulic pump and require electronic diagnosis instead; an independent with dealer-level diagnostic software can handle EPS faults on most MERCEDES BENZ vehicles. Dealers charge substantially more for hydraulic pump replacement with no quality advantage.

Yes — remanufactured power steering pumps are the standard replacement. Quality remanufacturers (Maval, Atlantic Automotive, Cardone) disassemble, clean and rebuild pumps to OEM pressure and flow specifications. Always replace the power steering fluid and flush the system at the same time — old, contaminated fluid will accelerate wear in the new pump. If the reservoir screen is integral to the pump, replace it with a clean one. For high-mileage MERCEDES BENZ vehicles, also inspect the high-pressure hose for internal degradation, as collapsed inner hose lining can restrict flow and cause symptoms similar to a failing pump.

Both affect steering feel but in different ways. A failing power steering pump causes heavy steering (particularly at low speed), a whining noise that increases with steering input, and fluid loss from the pump itself. A leaking steering rack loses fluid from the rack end seals, causing the fluid level to drop (heavy steering eventually) and leaving an oily patch under the centre of the car. A garage can identify the source visually with a pressure test. Pump replacement is cheaper; steering rack replacement is one of the more expensive steering system jobs.

At 2–5 hours of labour this is a substantial repair requiring specialist knowledge, proper lifting equipment and workspace. Professional completion is strongly recommended — use RepairFair's estimate to confirm the quote is fair before committing.
