I can check that. I replaced the fluid and put in the GM LSD fluid when I re-filled. There haven't been any leaks on my floor. Where could the fluid go?
There is a procedure on page 4B-11 of the service manual that describes my situation:
In somecase after extended expressway driving in warm ambients, a slip-stick condition occurs in the clutch plates of Saf-T-Track axles during right turns. This is recognized as chatter noise. When a customer comes in for his recommended lube change or at the first chatter complaint, flush the rear axle following the procedure below. If chatter recurs at a later mileage, add additive only.
Sounds like I should at least start with that procedure. This has been happening for some time but maybe this procedure will keep me going for a while longer until I can buy the Eaton unit above.
I would still like to know where to buy the clutch plates? Or how to search for them?
