Hey, I need some help if anyone knows the torque spec. for the 8.5 on my grand national....pinion nut....thanks....

until it takes 20-25 inch lbs (new) 10-15 in lbs (used) to spin the pinion yoke to properly set the pinion bearing load , usually that takes the pinion nut to over 100ftlbs (usually almost 200) but you need to check the preload by tightening a little and then testing the drag (only about 1.5 ft lbs of drag isnt a whole lot ) youll need an inch pound torque wrench to check

if you are replacing a yoke you should check the drag first and then return to that #

heres a lint that may help ,its not a gm 8.5 but the same principles apply and the simple scale they make should be fine for testing the drag

If the sleeve is already crushed id just make sure its tight. To crush the sleeve it takes a lot of torque.
