27 10 070 Replacing output flange on transfer box at rear (ATC450)

WARNING: This page is about a different car, the 2010 BMW X5, 2009 BMW X5, 2008 BMW X5, and 2007 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

After completing work, check transmission oil level and top up if necessary.

For this transfer box, use approved transmission oil only.

NOTE: Replace output flange only together with a new radial shaft seal. Operations for removing output flange are identical to replacing radial shaft seal.

NOTE: Thickness of new shim must be determined before output flange is installed.

Determine and note down dimension A of output flange (previous and new).

Subtract dimension B from dimension A of output flange (new).
Then subtract result of step 2 from result of step 1.
