What to check when buying a used Mercedes-Benz B-Class steering box
A used steering box that fits one vehicle won't always fit another - even within the same model range. These questions help breakers match stock to your exact vehicle before they quote:
- State whether it's manual or power-assisted

Fitment questions
Does the Mercedes-Benz B-Class have a steering box?
No — the B-Class (all generations, W245 2005–2011 and W246 2012–2018) uses rack-and-pinion steering, not a steering box. A steering box is a recirculating-ball unit typically found on older or body-on-frame vehicles; the B-Class never used one in any engine or trim variant.
What steering part should I actually be looking for on my B-Class?
You most likely need a steering rack (also called a steering rack and pinion assembly), the power steering pump if your car has hydraulic assistance, or the electric power steering column if it has EPS — the W246 generation moved to electric power steering. When searching on Findapart, ask breakers for a 'steering rack' or 'EPS column' and quote your registration so they can confirm the correct unit.
Will a steering rack from a 2009 B-Class fit a 2013 B-Class?
Almost certainly not — the 2009 car is the first-generation W245 (2005–2011) and the 2013 car is the second-generation W246 (2012–2018), which is a completely different platform. Confirm with the breaker against both registrations, but a cross-generation swap is very unlikely to be compatible.
Does the trim level — Sport, SE, AMG Line — affect which steering parts I need?
Trim level does not affect the fundamental steering rack or EPS column fitment on the B-Class; those parts are determined by generation and whether the car has hydraulic or electric power steering. Be aware that AMG Line models may have different steering wheel or column stalk cosmetics, but the core steering components follow engine and generation, not badge.
Does engine size affect which steering rack a B-Class needs?
It can do — higher-output engines on the W246 (such as the B200 and B220 variants) may carry different power steering calibration or unit ratings compared to smaller-engined models like the B160 or B180, though the physical rack design may appear similar. Always give the breaker your full registration rather than just the engine size, so they can cross-reference the exact part number against your car.
I've been quoted a steering box for my B-Class — is that right?
No — if a seller is listing a 'steering box' for a B-Class, that is almost certainly mislabelled; the B-Class has never been fitted with a steering box in any variant. It is likely they mean a steering rack, EPS motor and column assembly, or power steering pump, so ask the breaker to clarify exactly what the part is and confirm it against your registration before purchasing.
