Why?

Most BMW axles from 07 onwards were manufactured with a friction-welded ring gear and differential. This can cause some headaches for installation concerning vehicle downtime while the factory differential/ring gear is separated by precisely machining the parts away.

Wavetrac Europe has now solved this for the BMW 4' F83 M4 equipped with the 3310809473 3.46. Have a different axle? Contact our team with your VIN to see if we can offer something for you. Contact Us

Axles can vary by model, trim and market supplied. Please supply your VIN prior, at or after checkout so out team can cross-check what axle BMW specify your car was fitted with from the factory, ensuring you are supplied with the correct axle.
