8.8" friction modifier needed ?
Is the 8.8" rear diff, limited slip?
I'm about ready to drain fluid and refill and need to know if R. Diff also needs
friction modifier?
What is the proper gear oil for the 8.8?
The owners manual is very vague about which Differential came with the truck.
The R. Diff is shuttering during cornering after highway driving.
It shutters harder when towing trailer.
I figure I will try new gear oil and go from there.
thanks,
Adipose
