Second Hand Mercedes-Benz EQS Gearbox Mount

No — the EQS is a fully electric vehicle and does not have a traditional gearbox or transmission in the conventional sense; it uses a single-speed reduction unit integrated directly into its electric drive module, so there is no separate gearbox mount as you would find on a petrol or diesel car. If you are hearing or feeling a vibration or knock from the drivetrain area, the part you may actually need is a motor mount (also called an electric motor mount or drive unit mount), which serves a similar function of isolating the electric motor from the bodyshell. A breaker who specialises in EV or Mercedes-Benz dismantling will be able to help you identify the correct mounting component against your registration.

It is unlikely to be correct terminology for this vehicle, as the EQS has no conventional gearbox and therefore no gearbox mount exists for it. The correct part is almost certainly an electric motor mount or drive unit mount, which locates and cushions the single-speed electric drive assembly. We would recommend going back to the supplier and confirming they mean a motor or drive unit mount specific to the EQS platform, quoting your registration so they can verify the exact part.

The EQS uses electric motor mounts or drive unit mounts to secure the front and/or rear electric motors to the subframe or bodyshell, depending on whether your car is rear-wheel drive or four-wheel drive (4MATIC). Because the EQS was sold in RWD and AWD variants from its launch in 2021, the number and position of these mounts differs between drivetrains, so you should quote your exact model designation and registration to a breaker to ensure you get the right mount for your specific configuration. These are the parts to search for rather than a gearbox mount.

The EQS (V297 platform) launched in 2021 and has run as a single generation without a fundamental platform change through the production years covered, so there is a reasonable chance of compatibility within the same drivetrain variant — but whether a specific motor mount changed in specification between 2021 and 2023 is something you should confirm with the breaker against both registrations, as ancillary and mounting components can be revised mid-production without a visible external change. Always give the breaker your exact VIN or registration so they can cross-reference the part number before purchasing.

Trim level — whether your EQS is a 350, 450, 580 or the AMG EQS 53 — does not in itself dictate the mount design, but what does matter is the drivetrain configuration tied to that variant, specifically whether it is rear-wheel drive or four-wheel drive (4MATIC), as this determines how many drive units are fitted and where they are mounted. The AMG EQS 53 4MATIC+, for example, has a different twin-motor setup to a standard EQS 450+, so the mounts may well differ. Give the breaker your full model designation and registration rather than just the trim badge to ensure the correct part.

Because the EQS is a relatively recent and low-volume model, used mounts are less common than on mainstream petrol or diesel cars, but specialist EV dismantlers and Mercedes-Benz breakers are the best starting point. When contacting a breaker, quote your registration, VIN, and whether your car is RWD or 4MATIC, as the drive unit configuration directly affects which mount is needed. Findapart can connect you with breakers who can quote on the correct motor or drive unit mount for your specific EQS variant.
