Weird noise from eaton
I posted this in the Gears an axles section and had no help.
When my eaton gets to normal operating temperature it makes a "moaning" sound every time I turn which is really annoying. I added a second bottle of trans-x limited slip additive and it helped a little but not enough. I'm thinking of changing the oil AGAIN to see if it helps. Got any ideas??

No, The guy who installed it put trans-x and it wasn't doing it. The rear end was leaking so I changed the plug and gasket and that's when it started. I didn't have time to change the parts right away to fix the leak, so I kept adding oil to it until I was abled to fix it. I'm thinking that may have caused it by not having enough limited slip in it.

yup, Eatons have a carbon fiber clutch i believe. obviously you will hear a noise from your rear end if you corner hard. so many people say put the GM additive in with the Eaton. no need to. i was told by 2 popular Eaton dealers to put in 85/140 gear oil without additive. i put in 3 qts of valvoline 85/140 synthetic gear lube, and nothing else. never a problem. i have a valvolone rep that lives about 5-6 doors down from my house, and he agrees.
