Rear Diff Whine
Hi all,
I'm running a '10 C4S Cab with 23k km on it and am getting a kind of whine from my rear diff only when I am pulling a U-turn. In fact its more of a low pitched whistle, kind of like a dry bearing noise.
I understand that when Im doing a U-ey, the rear diff is working probably as hard as it ever will need to with both rears wheels going at very different speeds, so it may just be this speed differential that's causing it.
I wondered if Im being over picky (Ive only had my pcar a month) or if anyone else with a C4S experiences the same and I shouldn't worry.
The car was purchased from an OPC and has just had its major service, surely diff oil levels would have been checked and confirmed during this?
Any thoughts much appreciated
Cheers

Dealers make mistakes too. Warranty? Just serviced? Take it back in and have it re-checked. Are there any additional additives added to a Porsche diff? I know my GM truck does.
