: The topic of the rear AGAIN

02-06-05, 10:37 PM
Alright i know this topic has been beat up on this board many times but I need to share and get some feedback. Gear oil changed with MT90 Redline, only 1200 miles and only whines when fully warm. If car is cool and only driven for 20 minutes or so no whine? Normal? A little annoyoing I must say.:confused:

Whine is always more pronounced when the rear diff heats up, at least in my experience(s).

If its not in the service manual to change the gear oil at that low milage, i will not do it. Why should you have to shell out the money for a car under warranty?
