Second Hand Mercedes-Benz EQA CV Joints

Yes, CV joints do exist on the EQA. The EQA is a fully electric vehicle built on a platform derived from the GLA, and like most front-wheel-drive and all-wheel-drive electric cars it uses CV joints to transfer drive from the electric motor(s) to the wheels, so this is a genuine part to be looking for. On the standard single-motor EQA (front-wheel drive) you will have CV joints on the front axle only, while the dual-motor EQA 4MATIC variants also have CV joints at the rear. Make sure you tell the breaker which axle you need and whether your car is 4MATIC or not.

The Mercedes-Benz EQA has been produced as a single generation since its launch in 2021, with no full model-generation change as of 2024, so year-to-year compatibility within that run is broadly likely. That said, Mercedes did introduce a facelift to the EQA range during its production life, and whether any running-gear components changed across that update is something you should confirm with the breaker against your specific registration rather than assume. Always give the breaker your reg so they can verify the exact part against their dismantled vehicle.

Yes, the motor variant matters here more than trim name alone — the EQA 250 is front-wheel drive and only has CV joints on the front axle, whereas the EQA 300 4MATIC and EQA 350 4MATIC are dual-motor all-wheel-drive models and have CV joints on both front and rear axles. Within the same drivetrain layout (for example comparing two EQA 300 4MATIC cars), cosmetic trim differences such as interior spec or AMG Line styling do not affect CV joint fitment. Always confirm with the breaker whether the joint is NS (nearside, driver's side in the UK) or OS (offside, passenger's side), and which axle you need.

No, a front-wheel-drive EQA 250 does not have rear CV joints at all, so there is nothing to take from one for your rear axle. The rear axle CV joints are unique to the dual-motor 4MATIC variants, and you will need to source from a breaker dismantling an EQA 300 4MATIC or EQA 350 4MATIC. Tell the breaker your full registration and confirm the output power of your variant so they can match the correct part.

The EQA and GLA do share an underlying platform, but the EQA uses electric motors rather than combustion drivetrains, which means the CV joint assemblies and their interfaces may differ significantly from those on a petrol or diesel GLA. You should not assume GLA parts will interchange, and this is firmly a question to put directly to the breaker, who can compare part numbers against your registration. Never fit a part without the breaker confirming compatibility against both vehicles.

Yes, it matters and you must specify. CV joints are handed (nearside or offside), and on many vehicles the driveshafts are also different lengths between the two sides due to the position of the differential or motor unit, making them non-interchangeable. On the EQA this is particularly likely given the packaging of the electric motor and power electronics, so always confirm with the breaker which side you need — NS is the driver's side in the UK, OS is the passenger's side — and verify against your registration.
