1995 k1500 rear diff first change 150k miles
My question is limited slip oil or full synthetic for the rear differential?
What kind for the front?
Thanks all............

 

Always use synthetic when you can, it is a superior lubricant. Read the bottle of lube, it will tell you if it has an additive for limited slip differential use.

 

Thanks for the response!
Another subject....This info my help someone. My transmission would not shift and the Tach would not operate...(no service engine light on) the problem was the ignition switch in the steering colum...seems the transmission was not getting voltage to operate. Replaced the switch and transmission & gauges fixed!
Just thought I would pass this info on.

 

thanks for the info Tex.
