Help with rear end lubricant (93 Tracker)
Decided to look up in my service manual (Actual GM manual) to see what lubricants were called for in the manual. The only thing stated was a GM P/N 12345836. Called my local auto parts store to see if they had a cross reference or anything that would tell me what to use. No luck. Then called the local Chevy dealer, no luck again they even said the p/n was no longer valid and that they had no idea what to use. All I know if that it is a synthetic fluid. The manual trans call for a syn [img]images/graemlins/confused.gif[/img]thetic 75w-90 GL4, would the rear ends use the same?
