- Fits: 2017-2019 BMW 430i and other vehicles

A clicking noise in turns, grease thrown from a torn boot or vibration under load can mean an axle is worn. These signs alone do not prove the axle is the problem, since a worn wheel bearing can make similar noise. Rear axles are normally changed as a pair, but this listing is one shaft for the rear right, and the rear left is a separate part. The 2017-2019 BMW 430i takes one for this side.
Fits
The 2017-2019 BMW 430i, the 2017-2018 BMW 330i and the 2012-2016 BMW 328i take this axle shaft, and so do other vehicles. If your BMW is not one of these, look for it in the "Vehicles it fits" section.
