Anyone ever check the temp of the center diff? I changed the fluid in mine last night from 7k to 10k and added just a drop or two of 30k to top it off, I noticed it was 220°F right after my last run today when I was checking my motor temp. The motor was only in the 170°F range which made this seem even stranger, I'll rebuild the center diff based on these findings, however I wonder what normal Diff temps should be? beside the high temp reading everything else appeared to be good - no sign of a leak, diff seemed to be smooth and the car was hooked up after I changed from 4.5° rear toe in to to 5° of rear toe-in. I'm guessing the drop or two of the 30k fluid might be the reason for the high center diff temp but, I'm not sure why. Appreciate any insight to this or what to avoid doing in the future.
