It's Making crazy sounds on low speed turns and
When go's away -

Just check and don't see any missing spider gears or anything bad inside -

Been told to use 80w90 none synthetic w/ 4oz gm friction modifier

Let me know what you guys think - thanks

Mine was doing the same. I had mobile 1 synthetic in there and was told I wouldn't need the friction modifier. I ended up adding a bottle of the Ford stuff in with the mobile 1 and it was much more tolerable.
