The yoke was shiny where the seal mated against it but there was no wear, so I didn't use the sleeve. The inside of the yoke at the pinion nut was wet with oil so I think it was actually leaking through the splines not at the seal. I used some oil resistant locktite sealer on the splines and under the washer to hopefully solve it.
The pinion nut came off too easy, like it wasn't torqued properly. I torqued it to 100 foot pounds and the align chisel marks I made showed approx 1/8 turn tighter than where it was. There were rubbing marks on the bearing and end of the yoke like it was slipping. So hopefully fully torquing it will solve that. I checked for excessive preload by turning the yoke by hand easily.
On the transmission end, I removed the stock size seal that I had just replaced and used one that was 20 thousands smaller to compensate for a worn transmission yoke. The used yoke I bought is too big at the u joint and hits the tunnel.
We'll see how it all works out next week when I hit the bass pro car show at foxboro, about a 120 mi round trip.
I also have a clear polycarbonate diff cover I'm going to put on soon to make it easy to monitor oil level.
