7.25 axel new pinion bearings set up

first thing to try ,, when torquing the pinion nut go in steps of say 50 lbs/ft and then give the yoke a couple turns forward and reverse , this lines up the bearings and their races then go to 100lbs/ft and turn the yoke and so on to the final torque . if at say 100 lbs/ft you have to much preload you are going to have to replace the crush sleeve and set the preload to the 20-25 lbs/inch for new bearings. there is no real torque spec when using a crush sleeve ( although they say 175 lbs/ft minimum to crush the sleeve ) as once the sleeve is crushed to the correct preload spec you are done you can pull up to 300-500 lbs/ft to crush that sleeve,,, now if your diff uses shims to set the pinion bearing preload then you have to add some shim to bring the preload to spec then torque the nut to the 240 lbs/ft spec.
