Second Hand Mercedes-Benz EQB Steering Box

No — the EQB uses an electric power-assisted rack-and-pinion steering system, not a steering box. A steering box is a recirculating-ball or worm-and-sector unit found on older or heavier vehicles; the EQB never had one fitted in any variant or market. If you need a steering component, you are most likely looking for the steering rack, the steering column, the power steering control module, or the EPS motor assembly instead.

The part you want is a steering rack (rack and pinion assembly), not a steering box. The EQB was launched in 2021 as a single generation based on the GLB platform, and all variants — including the EQB 250, EQB 300 4MATIC, and EQB 350 4MATIC — use electric power steering with a rack-and-pinion setup. When searching on Findapart, use 'steering rack' or 'steering rack and pinion' as your search term to get accurate quotes from breakers.

This is worth checking carefully with the breaker, because the EQB 250 is front-wheel drive while the EQB 300 4MATIC and EQB 350 4MATIC are four-wheel drive, and the steering geometry and rack configuration can differ between drivetrains. Always give the breaker your full registration number so they can verify the exact part against your vehicle rather than assuming all EQB racks are interchangeable.

Trim level alone does not affect steering rack fitment on the EQB — the rack is determined by the drivetrain (front-wheel drive or 4MATIC four-wheel drive), not by whether the car is Sport, AMG Line, or another trim grade. You may find cosmetic differences around the steering column shroud or steering wheel between trims, but the rack itself is not trim-specific. Confirm the drivetrain variant of the donor vehicle with the breaker against your registration to be sure.

The EQB has been a single generation since its 2021 launch, and while minor updates have been applied over the model's production run, no major mid-generation platform change that would obviously affect steering rack compatibility is widely documented. That said, it is always safest to give the breaker your registration plate and the year of the donor vehicle, because subtle engineering changes can occur without a formal facelift announcement, and the breaker can cross-reference part numbers to confirm compatibility.

Tell them you need a steering rack or EPS (electric power steering) component, not a steering box, as the EQB does not have a steering box. Give them your vehicle registration number and, if possible, the registration of the donor EQB they are breaking, noting whether it is a 250 (front-wheel drive) or a 4MATIC (four-wheel drive) model, as this is the key fitment variable. A reputable breaker will cross-reference part numbers before confirming the sale.
