741 - crush sleeve and shims?

the seal will maybe add 2-3 in/lbs to the rotating torque --- the reason for the doubling of the torque was when you set the initial preload before installing the seal you must torque the pinion nut to at least 150 ft/lbs to get an accurate reading of the preload -- then when you do the final assembly the torque will be the same except for the 2-3 in/lbs for the seal.

That's a good theory on your part. I learned a long time ago you don't check your preload at a hundred and fifty pounds if your pinion nut is supposed to be at 200 to 250. Because you get a false reading and when you do your final setting of The pinion nut it will be off. I checked mine at 200-210 and it was a 20 inch pounds then I installed the seal retorqued it with red Loctite to 210 foot pounds and I was at 40 inch pound. So don't use a hundred fifty pounds to test because it's inaccurate.
