Hi,
My mechanic thinks that the whining noise on my 316 auto is from the diff.
He wants to change the oil and add some diff additive to see if that cures the problem.
what oil is used in the diff? 80/90 gear oil / atf ??

Most likely your pineonbearing is worn out. You can use 75w90.

mines noisy. needs to get worse before i'll do anything about it. might change the oil on it at some point.
bung some hypoid 75w90 in it, if that doesnt quieten it down then its knackard.
