Used Mercedes-Benz GLA Axle

The first-generation GLA (X156) ran from 2014 through to 2019, so a 2014 and a 2018 car sit within the same generation and axle fitment is broadly likely - but engine size can affect the axle spec, so make sure the donor car matches your engine. Confirm the exact interchange with the breaker against both registration numbers before buying.

No - the X156 (2014-2019) and the X247 (2020 onwards) are different generations with different platforms, so axle parts will not cross over. Always source from the matching generation and confirm with the breaker against your registration.

This question spans the generation boundary: 2019 is the final year of the first-generation X156, while 2020 marks the start of the second-generation X247, and the two platforms are not the same. Even though the years are close, you should not assume compatibility - take both registrations to the breaker and let them confirm before you commit.

Trim level does not affect axle fitment on the GLA - SE, Sport, and AMG Line are cosmetic and equipment packages rather than mechanical variants. What does matter is engine size, since different outputs can carry different running-gear specs, so match the engine to the donor car. Confirm with the breaker against your registration to be sure.

Yes - larger or more powerful engines can put greater demands on the drivetrain, so the axle spec can differ between, for example, a 180 and a 250 or an AMG 45. Always tell the breaker your exact engine variant as well as your registration so they can pull the right unit.

Front and rear axles are entirely different parts and are not interchangeable, so be precise when asking for a quote. If you need a front axle, also check whether the donor car matches your engine size, as this can influence the spec. Confirm everything with the breaker against your registration before purchasing.
