Used Mercedes-Benz GLA Wheel Hub

The Mercedes-Benz GLA first generation (X156) ran from 2014 to 2019, with a facelift arriving in 2017, so both years sit within the same generation — however, whether the hub itself interchanges across that 2017 facelift boundary is something you should confirm with the breaker against your exact registration, as running-gear components can be updated mid-generation. Give the breaker your reg and ask them to check the part numbers on the unit they have. Never assume fitment without that check.

Yes, engine size can matter because larger or more powerful engines often run bigger brakes, and the hub has to match the brake setup on your specific car. A GLA 200 and a GLA 250 may look similar but could carry different hub and bearing assemblies to suit their respective brake sizes. Always tell the breaker your exact engine variant so they can cross-reference accordingly.

Trim level alone — whether your GLA is SE, Sport, AMG Line, or Urban — does not affect wheel hub fitment; the hub is determined by the generation and engine size, not the trim badge. That said, if you are sourcing a hub complete with a brake disc or caliper, be aware that different trims can have different brake specifications, so mention your trim to the breaker as a useful cross-check. The hub itself should not differ on trim grounds.

No — the second-generation GLA (H247) launched in 2020 on a substantially different platform from the first-generation X156 (2014–2019), so the two generations are not interchangeable. Make sure you and the breaker are clear which generation you need before any money changes hands. Quoting your registration is the safest way to avoid a mismatch.

Yes, you must specify nearside (NS, passenger side) or offside (OS, driver side) when ordering a wheel hub, as the ABS sensor wiring and bearing orientation can differ between left and right. Tell the breaker which side you need along with your registration so they can pull the correct unit. Getting the wrong side is a common and avoidable mistake.

The GLA X156 facelift arrived in 2017, so a 2017 car could be either pre-facelift or post-facelift depending on exactly when it was built and registered. Whether the hub specification changed across that facelift boundary is something you should confirm with the breaker against your specific registration rather than assume from the year alone. Giving the breaker your reg number is the most reliable way to get the right part.
