9'' pinion nut spec.
Don't mean to disagree,but I do it for a living....9'' you must change crush collar and torque until it takes 10 to 20 inch lbs.of drag to turn yoke without any axle or brake drag ,same for dana 44 if it has crush collar,most have spacer and shims if so tighten to 200lbs. same 10 to 20 in lbs.drag,it will take over 300ft.lbs.on 9''to start crushing collar,go slow,if you get over 30 in.lbs.on either one ,pinion brgs.won't last 500 mi.
