Now for the replacement spindle, i needed to polish off .0005 off both diameters for the bearings to fit on them, I used a little 1000 grit followed by a little 1500 grit, being very careful to take the surface down evenly.

So i got the passenger side spindle mounted and new prevailing torque nuts, mounted the hub and rotor and preloaded the inner bearing while spinning to 50ft#, backed it off 3/8 of a turn and installed the locking washer, and installed the outer nut and torqued it to 50 ft# per the service manual.

There is a lot of discussion about whether 50# is enough for the outer nut torque, i have read discussions saying 80#, 130# 150# My Clymers said 175# and another said to reef on it until you cant reef on it anymore.. so I figure i'll run it for a little at 50# per the pdf and keep checking the hubs for warmth then open the hubs back up and re set the bearing preload after a few hundred miles or so, and if it feels like they stayed tight i'll use 50# again, if not i may increase it a little .

Again my hats off to the hack that worked on my truck before, he used a chisel to remove and install the hub nuts, and don't recall if i mentioned yet but my bearings were in fact not at properly preloaded, which is what ruined my spindles. I decided to grab my wet stone and stone the chisel burs off the flat surface of the nut and reverse it as the outer 4 slots were pretty hacked up.

Pic's to follow tonight.
