<E36> Differential / Road noise

[Anup Lakare <alakare@xxxxxxxx>]

Hello Group,

My '94 318i seems to be making rumbling noise after 10-15 MPH.  It seems to
be coming from the rear side, maybe from the diff. or from the road.  I have
this feeling that the noise has grown in the last few months.  I am not sure
if this rumbling noise is normal or if I need to replace diff oil or tires.
Currently I have Pirelli tires on and the diff oil was changed about 20000
miles ago.

Please let me know what is the best oil to use for the diff., it is a LSD
and what are the best tires to reduce road noise.  I live in Atlanta area,
so snow driving is not an issue for tire selection.

Thank you for sharing your experience.
