While in Moab this last week, I decided to take a look at the bolts holding my Superwinch (junk) hubs to the hub/rotor assembly flange as I'd been having trouble keeping them snug. Wouldn't you know, two of them where sheared off leaving the stud in the hub flange. I now only have two bolts (one was sheared off when purchased from PO) holding the hub to the mounting flange. I'd like to replace the '82 five bolt hub/rotor assembly with the 76-81 6 bolt and add Warn Premium hubs. Are bearings, wheel washers etc. cross compatible? What about the spindles? Thanks in advance!
