Overview
Not a steering rack or a hose set, the 21-120 is a power steering pump supplied with its pulley. Belt-driven off the engine, the pump pressurizes fluid that makes the steering light.
For an owner of the named ML350, buying the pump with its pulley avoids sourcing the pulley separately. The listing does not give any OEM numbers, pressure ratings or hose connection details, so the fit rests on the vehicle name in the title.
Who it's for
Owners and shops fixing the power steering on the named ML350 and engine. Anyone with a different year, engine or model has nothing in the listing to confirm a fit.
Pros and cons
- Pulley supplied with the pump
- Vehicle and engine named in the title
- Straightforward replacement part
- No OEM numbers listed
- No pressure or flow rating
- Hose fittings not described
- Brand and model fields repeat
Performance notes
The engine drives the pump through its pulley and belt, and the pump builds fluid pressure for the steering. Whine, stiff steering or leaks are the usual signs of a worn pump, and a new unit only helps if the fluid, hoses and belt are in good shape.
