rotational TQ for 9" pinion?
I'm having a little trouble with setting this thing up. I've got it either under 5 inch pounds or right around 25-30inch lbs of rotation tq. Cant seem to get it in between. Everthing is new as far as bearings and gears. I'm thinking a little tight (25-30" lbs) will loosen up after awhile. But im afraid it might burn a bearing up. WHat should i do?

25-30 rolling inch pounds is fine for a new assembly.
Its actually more of a finesse' thing... but correctly measuring pinion preload with a bar type torque wrench can be somewhat difficult. You are really seeing the initial break away torque and from there... is when it becomes difficult to maintain any for of constant measure.
And... it will loosen up a little... but if its assembled correctly... it wont be very much. 25-30 inlbs is good if that number is with the bearings being pre lubed with a higher viscosity assembly grease.
