there is a special tool by "kent-moore" we use at work to set pinion bearing torque... you will need this tool a half inch impact the right size socket and a dial torque wrench basically what you do is you install the bearings crush sleeve and pinion gear just like you would normally then the yoke, washer, and pinion nut... you then install the preload tool onto the yoke with two bolts and VERY VERY VERY VERY slowly run the nut down while holding the preload tool at the 9 oclock position... you then let the tool swing freely... the first couple times it will swing to about the 4oclock then swing back and eventually stop at the 6 oclock position... you will notice as you tighten the pinion nut EVERY SO SLIGHTLY with your impact that every time you swing the preload tool it will have less return when it swings then stops at the 6 o clock position you take your dial torque wrench and you want about 20-25inch pounds* of preload rolling torque if you do not have enough torque just BARELY hit the nut again and remeasure with the torque wrench until you have the right amount of preload.


*im not 100% certain the correct preload value but atleast thats what i do on GM trucks
