Mein Auto: 2006 X3
Transfer Case Issue 2006 E83

Just swapped out my transfer case with a used unit with only 20,000 miles. Mine had 118,000 miles and had been noisy for some time. Just disassmbled the old unit, the chain stretched and started to wear into the aluminum case. This is what all of the racket was under heavy torque. Seems that the bearings for the output shaft to the front driveshaft need replacement too, they growl a bit just turning them by hand.

This vehcile has never been driven hard so even though it 118,000 miles I am a bit suprised what I found when I opened up this transfer case. May now re-think my 2011 X3 purchase.
