Well, like you said, it takes an incredible amount of force to crush the crush sleeve. After using about a 5' cheater bar, I was finally able to get it dialed in. I had good luck getting it to budge about an 1/8" at a time, and crept up from 8 to 10 to 13 in. pounds. Lots of off and on the with the spanner wrench, and now I'm waiting for the RTV to dry. Another reason I opted to not change the pinion bearings was because the previous owners lived in the city. The backlash was still at the minumum spec of .005"
I can't believe that 1/2" breaker bar held, it was flexing inches! 500 ft pounds easy (I was almost hanging on a 5' cheater bar).
I just ended up letting red locktite soak on to the end of the nut for a little insurance, but I doubt the new nut needed it.
good times
