A rear wheel bearing assembly has the hub/drum 16, the spindle 18 and the rear wheel bearing 20 assembled as a single unit. This unit is fixed by means of bolts 24 to a bracket 14 of the vehicle suspension, 50 that the unit can be removed as a single entity, for access to the brake shoes for servicing. This has the advantage that good servicing access is achieved whilst avoiding any disassembly of the bearing, which could result in dirt getting into the bearing thus impairing its efficiency. Upon assembly, when bolts 24 are tightened, the outer race 28 is held rigidly to the bracket, and a back plate 22 is clamped between them. The inner race 30 rotates relative to the outer race 28 and is secured on the spindle 18. <IMAGE>
