I've bought a Torsen that will go in my 92 to replace its whining open diff. I also have the driveshaft and half shafts. It's out of an '02. My question is: do I need new halfshaft nuts, and if yes, are these the right ones? NUT (GJ21-33-042B) - $6.69 - GJ2133042B
Also, anyone know the driveshaft nut and bolt part numbers? If not I'll just call up Rosenthal and ask.
Anything else about the Torsen swap that I'm missing? The diff's half shaft seals look fine and I dont think I need to bother with the bushings.
Thanks!

It seems those are the ones.

New fluid for the diff, Redline, RoyalPurple, Amsoil...

Make sure there is grease inside the axle boots.

Make sure the drive shaft is balanced. Usually if the weights are on it and it's not damaged, your good.

Driveshaft looks perfect, no dents or scratches, weights intact. I was gonna put Mobil 1 GL5 in the torsen because that's what I have lying around. I'm not sure how to check the grease in the boots as they're sealed at both sides, and don't have any cracks...
