This axle uses studs with course thread in hub, and fine thread with a nut to hold axle shaft in place. Every time when removing axle shafts some of the studs remain in hub, and others thread out leaving its nut in place. When reassembled studs protrude from hub at various lengths. I have tried to secure them in hub with Loc-Tite which seems not to hold very well. It seam that this stud and nut method is not able to cinch down well enough for correct torquing. Could I convert to course thread grade 8 bolts, or they not strong enough for this application? Later model trucks look to be using bolts to hold axle shafts.
