Diff. lube

Diff. lube
I believe my 2005 C6 Vett has AC Delco synthetic oil in the Differential. I have been told to use only AC Delco Dexron LS Gear Oil 10-4034. Is this oil a synthetic oil and if not will it harm the differential that had synthetic in it before. Hearing lots of clunks coming from the Diff. and want to change the oil. Thanks.

Last month I had my 05 have it's 50,000 miles check-up including Diff and Trans fluid change at the Dealership, so I hope they would use proper fluid, they should know what to use.

The early C6 vettes (MY2005 thru 2008) were prone to rear differential clutch chatter due to the poor formulation of the factory gear lube. The GM solution finally arrived with the introduction of DEXRON LS diff fluid as factory fill for MY2009. There are long time corvette owners who will tell you that diff clutch chatter has been a problem even for older generation corvettes prior to the C6. Prior to DEXRON LS, many have stopped chatter with aftermarket fluids manufacturered by AMSOIL, Redline, RP, etc.
