See Figures 1 and 2
All front wheels and tire assemblies are bolted to their respective front hub and drum (or disc). Two opposed tapered roller bearings are installed in each hub. A grease retainer is installed at the inner end of the hub to prevent lubricant from leaking into the drum or on the rotor. The entire assembly is retained to a spindle by an adjusting nut, locknut and cotter pin.
The rear brake drum assembly is retained to studs on the rear axle shaft flange by three speed nuts. The wheel and tire mounts on the same rear axle shaft flange studs and is held against the hub and drum by lugnuts. The rear wheel bearing is pressed onto the axle shaft inside the shaft flange edge. The entire assembly is retained to the rear axle housing by the bearing retainer plate which is bolted to the housing flange. The inner end of each axle shaft is splined to the differential in the rear axle.

- Remove the lug nuts from the wheel studs, then pull the wheel and tire assembly off the drum or rotor.
- Place the wheel on the drum or rotor assembly.
