Angus ...My best guess is the Pinion bearing is going bye-bye...It is
the most common issue after the 3/4 slider hub cracking with these
tranny's. From my point of view, the sooner you deal with it the better
due to the increased wear to the ring/pinion from the sloppy
bearing...That and the fact that the 3/4 slider WILL go soon..It's their
weak point, so be ready to do a rebuild soon ($995 from me). Even with
Redline, they are getting tired at that mileage and need some TLC...Good
Luck
