Wheel Bearings Wheel bearings require cleaning, inspection, packing with grease or an oil change at each brake re- line. Wheel bearings should be lubricated in accordance with the vehicle manufacturers recommendations. They may either be grease packed or oil lubricated. A 1/4" pipe plug (see fig. 2) is located under the hub cap in the outer axle shaft flange. Oil filled wheel hubs should be filled to the level of this plug when it is in a position on the axle horizontal centerline. Grease packed bearings require that the section of the wheel hub between the bearing cups be filled to the level of the inner diameter of the bearing cups. The outer axle shaft inner bearing should also be packed with grease, if the hubs are not lubricated with oil. With the outer shaft out for access to the wheel bearings, disconnect the joint from the inner and outer drive yokes, and push the outer drive yoke from the bearing and seal. The bearing rollers are now accessible and may be packed by hand. Do not use anything to apply grease that would cut the seal. If oil lubricated, the bearing will receive its supply from the wheel bearing reservoir, and repacking is not required. See Section IV-B and Section VI-D, H and I for disassembly and reassembly of hubs and outer axle shaft. B. Universal Joints Universal joints should be lubricated at each chassis lubrication (approximately 1,000 mile intervals). Vehicles operated with the joints submerged must be lubricated at more frequent intervals. Apply until seepage is detected around each of the rubber cap seals. If all seals do not release lubricant, move the cross laterally in all four directions, then pull down on the bearing cap opposite the side that did not release. Apply lubricant until a flow appears.
