Used Mercedes-Benz EQB Gearbox Mount

The EQB is a fully electric vehicle and uses an electric drive unit rather than a conventional combustion engine and gearbox, so it does not have a traditional gearbox or a gearbox mount in the usual sense. The electric motor and reduction drive unit are supported by motor/drive unit mounts, which is the part you are most likely looking for if something in that area has failed. Search for an EQB electric motor mount or drive unit mount instead, and confirm the exact part description with the breaker against your registration number.

On the EQB the equivalent components are the electric motor mounts or drive unit mounts, which secure the electric motor and single-speed reduction gearbox assembly to the subframe or body. There is no multi-ratio gearbox and therefore no conventional gearbox mount as you would find on a petrol or diesel car. Tell the breaker your registration and describe the symptoms — vibration, clunking, or a sagging drive unit — so they can identify the correct mount for your specific front or rear axle motor.

Yes, it can matter, because the 350 4MATIC has two electric motors (one per axle) whereas the 250 and 300 are single-motor front-wheel-drive variants, meaning the number and potentially the design of drive unit mounts differs between them. The drivetrain layout is therefore the most important detail to supply, alongside your registration or VIN, so the breaker can identify the correct mount for your specific axle position. Do not assume a mount from a 4MATIC car will suit a single-motor car or vice versa.

The EQB (X243) is a single generation that arrived in the UK from around 2022, and within that generation mid-production mounting changes are possible even when the body looks identical. Because the EQB is relatively new and production details can vary quietly year to year, you should confirm cross-year fitment directly with the breaker against both registrations rather than assuming any two model-year cars share the same mount. Providing your VIN to the breaker is the safest way to verify compatibility.

No, trim level does not affect the drive unit mounts on the EQB; AMG Line, AMG Line Premium, and AMG Line Premium Plus are specification packages that change cosmetic and comfort features but do not alter the motor or its mounting hardware. What matters is the drivetrain variant (250/300 single-motor versus 350 4MATIC dual-motor) and the model year. Be aware that a mount pulled from a different trim car may carry minor surface differences such as brackets or heat shielding, so confirm the specific part number with the breaker against your registration.
