A stub axle end allows replacement of a damaged spindle without replacing the entire axle beam. The #84 spindle configuration determines the required bearing and seal combination. Bolt pattern must match the trailer wheel exactly; 5 on 4.5" is measured across opposing studs.
Welding alignment and spindle orientation are critical to prevent uneven tire wear and tracking issues.
