CLEANING AND INSPECTION AXLE COMPONENTS Wash differential components with cleaning solvent and dry with compressed air. Do not steam clean Wash bearings with solvent and towel dry, or dry with compressed air. DO NOT spin bearings with air. Cup and bearing must be replaced as matched sets only. Clean axle shaft tubes and oil channels in housing. faces on the bearing rollers or the roller contact sur- • Bearing cups must not be distorted or cracked. • Machined surfaces should be smooth and with- out any raised edges. • Raised metal on shoulders of cup bores should be removed with a hand stone. • Wear and damage to pinion gear mate shaft, pinion gears, side gears and thrust washers. Replace • Ring and pinion gear for worn and chipped teeth. • Ring gear for damaged bolt threads. Replaced as a matched set only. • Pinion yoke for cracks, worn splines, pitted areas, and a rough/corroded seal contact surface. • Preload shims for damage and distortion. Install new shims, if necessary. TRAC-LOK Y Clean all components in cleaning solvent. Dry com- ponents with compressed air.
