Mercedes-AMG Power steering pump replacement

The cost of power steering pump replacement on a Mercedes-AMG varies by model, engine size and parts quality. Use RepairFair's free estimator to get an accurate price for your specific car.

Each Mercedes-AMG model sits in a different vehicle segment (compact, mid-size, SUV) and has a different engine configuration. Larger, more complex or more premium vehicles require more expensive parts and sometimes more labour time. Select your specific model for an accurate estimate.

Power steering pump replacement on a Mercedes-AMG typically takes 2–5 hours of labour. In practice, most garages will complete the job within a half or full working day depending on their schedule.

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-AMG 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-AMG models. The job requires no specialist software. Electric power steering (EPS) systems — now common on newer Mercedes-AMG 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-AMG 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-AMG 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.
