OK, I've decided on the Trutrac. It seems that the torque-distributing diffs (Torsen) have the best performance under braking and that is where I need the most improvement.
Eaton recommends dino oil only, no synthetic. The factory weight is 75W-90. Any recommendations on brands? Is the weight OK for race use?
I am planning on replacing the ring gear bolts and probably the diff carrier bearings. Can I get the bearings off the old diff carrier and reuse them? Any tricks to getting the bearing races out of the housing?

If it's a new carrier without bearings already on it, buy new bearings and get those pressed on. I wouldn't try to remove the ones on your current carrier to try reuse them, not worth it. The races fall out when you remove the diff bearing caps off the housing.

Now is not the time to skimp. Do it once and forgetaboutit ...
It's easy to take $1000 worth of nice parts and turn them into metal dust in very short order.
Also make sure you order model specific. Not all 10 bolts are the same.
Redline diff fluid. I use 80W120 because the 75W90 was puking out the vent, especially in August.
