177 ft lb nut backed off!!?? I guess something went wrong somewhere, glad you got it fixed pretty quick though
Yeah, no idea how. Maybe vibrations over 40k miles and lack of loctite. No idea if I actually properly torqued it way back when either. Snapped the hub right off the bearing like I've seen others do
Be sure the grease seal is still in place and not deformed.
Everything was in good order when I put her back together. Replacing wheel hubs isn't anything new to me, I replace them on other trucks all the time, just never had one snap on me personally. The one that I bought is a pos China one. I'll be buying a timken and throwing this one in the tool box as a road side spare
