hi guys,
i had my diff rebuilt with new bearings, seals & new nismo shims for my r32gtr (2 way diff).
prior to having it rebuilt, it used to make a humming noise between 60-90km...since the rebuild it makes the same noise but not as bad.
what could this be? maybe the fresh oil helped with some of the noise?
or is it normal for a 2way diff to make this sound?
if i have the radio on medium level i cannot hear the diff, im just really fastidious when it comes to my gtr
thanks
marko
