Bingo, mine always clicked around corners, changed the fluid and added some GM Limited Slip Axle Additive (#1052358) and no more clicky. I'm sure any brand works but I happen to work at a dealership, employee discount ftw.

If its popping the friction plates are not releasing as they should when you corner. I bought my last bottle from NAPA....

An old mechanic friend of mine called it "fish oil", and it was from GM. I think fish oil smells better then the additive, but the GM stuff works really good.

The rear I had the posi in was an 8.2, 10 bolt. I yhink it's a 2 serries carrier. Does anyone have any other info about this old thing?

That was in the '70's.



1870's?

Used to use that stuff in Saragossa.

Or was it Sarasota?

It came in a bottle...

Maybe it was a tall bottle.

Or was it a can?
