OE 0024668401 — Hydraulic Power Steering Pump for Mercedes-Benz

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest suspension, steering & brake reference and narrow by build year. Send photos and we will cross-check the number for you.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a hydraulic power steering pump the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Position depends on the platform. On most Mercedes-Benz applications the hydraulic power steering pump sits on the suspension, steering & brake assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

A supersession happens when the maker revises a hydraulic power steering pump and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 0024668401 we list the current reference; ask our desk for written confirmation before a large order.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.
