I ignored it thinking it was just a throw-out bearing because it went away with the clutch pedal depressed, and the hub eventually separated from the disc. I ended up having the disc properly rebuilt by a local clutch manufacturer. My advice is to get that disc out of there asap.

As far as oils...Mobil-1 Full Synthetic 10W-30 in the trans, and Mobil-1 Full Synthetic 75W-90 in the x-fer, 5 years of running thos
e, 5 years of perfect shifting (with massive amounts of abuse). Prior to the 10W-30 I ran 75w-90 and 2nd gear would grind sometimes.
neiice, i'm going to have to come back and read this a couple more times.. sounds like a good plan.

do you remember what the clutch service was called, and what you payed?
