8 3/4 questions

They are many ways to get the right answer Alot of the rear diff work is touch feelie ... That is why a lot of people do not do the work... It scares most people to build something where the specs can be referenced differently by manual etc. The bearings have to be tight enough so there is NO move ment and enough preload to suspend the unit too much preload and you will prematurely wear the bearings and stress the caps etc.

Pinion is checked with out a carrier in place there is a rating for USED bearings 10-15 inch pounds of rotating torque and new bearings slightly more at 20-25in pounds. Each manufature has different ratings etc. But when you do many you just get a feel for all this and it becomes second nature.

742 does not have a crush sleeve so it will take plenty of torque on the nut. IF your bearing feels tight you must add shim to the solid spacer shim and try again. Crush sleeve is usually easier as the torque rating is what ever it takes to crush the sleeve and get the preload...NEVER loosen the nuts when doing crush sleeve after getting your p[reload or you crush sleeve is used up. :( Bad thing about crush sleeves...lol. :) Jim
