Diff

[drudevernon]

Hi guys, anyone that have experience of a noisy diff of the E90 320I. My car is still driving normal, just the diff that is little bit noisy.

Can it be fix or must the diff be replaced. Can't wait for your positive feedback

Check bearings... My colleague at work had a noisy E90 323i diff... turned out to be the bearings on carrier unit needed replacing... rebuilding will be more expensive than buying a 2nd hand diff but the 2nd hand diff can end up having the same issue down the line...
