Default Re: 2003 316cdi diff noise

It does look good, not much wear at all, I still think the pinion bearing may need replacing as there is a small amount of play in it.
I took the diff cover off on the last fluid change a few years ago hence the silicone gasket.

What would cause a similar whine as a pinion bearing but coming from the gearbox?
I did a gearbox oil change about 18 months ago and noticed the whine was not as loud afterwards.
