Just continuing some trending with this OEM stock Torsen diff. I didn't plan to change it so soon. But since I had it on jack stands for tranny fluid change, I thought I'd change the diff and engine oil too.
This diff holds 0.81 quarts total fluid, so it gets a good workout!
The most recent UOA and VOA were done by Polaris Labs Houston. The previous testing of 1605 (SAE110) and 607 (SAE90) were done by Blackstone Labs.
I apologize for not getting a V100C reading. Polaris is a new lab for me and we're going through some growing pains.
