WARNING: This page is about a different car, the 2013 BMW X5 M, 2012 BMW X5 M, 2011 BMW X5 M, and 2010 BMW X5 M. However, it is still accessible from the selected car via links, so may be relevant.

Shaft seal and circlip must be replaced!

Installation note:

Clean shaft seal race on drive flange thoroughly.

Push drive flange into rear axle final drive as far as it will go and turn. Press in drive flange further until circlip can be heard and felt to snap into place.

The inner design of the differential causes a small, axial play of the drive flange - this play does not imply any damage.

IMPORTANT: High installation forces indicate that the gearing on the drive flange/differential bevel gear is damaged/deformed!
