2002 Chev 2500HD, 58,000 miles. Mobil-1, 75-90. Third change--
First change was when new after 500 miles. This change seems very early since the fluid only had about 25,000 miles on it. I was getting chatter on tight turns. I was told the fluid needed to be changed, but the chattering continues on tight turns
no improvement
 
2007 Lincoln Mark LT, 50k miles. First change of front and rear differential hand transfer case. Fluid was Motorcraft syn. for front and rear plus friction modifier due to limited slip. Transfer case was Motorcraft transfer case fluid.

I'm really surprised, I would've thought the friction modifier in SAF-XA (Sturaco 7098) would work against the the Torsen biasing quickly.
