Rear noise?

Yeah i'd definitely get some fresh fluid in there.. make sure you put in the friction modifier as well.

FYI, check out our site sponsor Synthetic Advantage; they have the gear oil and additive you need

Fresh gear oil certainly won't hurt. However, the ELSD has spider gears with a clutch pack next to them to lock the axle left-to-right. It's not like a posi that clicks or ratchets around a turn. I believe the clutches only engage and lock the axle when slippage is sensed. I'm not so sure that what you're describing is coming from the diff.

Good luck with the hunt!

There have been reports of QDII diffs chattering due to both lack of maintenance and not using the LSD additives. Anytime you're turning the clutches need to slip against each other, however pressure is not applied to the clutch packs unless slippage is sensed. But they are still in contact with each other.

Its an easy place to start especially since the fluids supposed to be changed every 30k miles (depending on which schedule you're referring to)

sounds like I'll be getting the rears fluid changed this weekend. I need an oil change anyways. I'll get them done both this weekend then. thanks.Frank
