Pinion Bearing Preload

  1. Place preselected shim on pinion shaft. Press bearing onto shaft until bearing and shim are firmly seated against shoulder of shaft. Install new collapsible spacer on pinion shaft.
  2. Lubricate bearings with axle lubricant. Install front pinion bearing in housing. Install new pinion oil seal. Insert companion flange into seal and hold firmly in place.
  3. From rear of carrier housing, insert pinion shaft into flange. Start a new pinion nut on pinion shaft and gradually tighten pinion nut (hold flange).
  4. Check bearing preload often. As soon as preload is measured, turn pinion shaft in both directions several times to seat bearings.
  5. Tighten pinion nut and continue to measure pinion bearing preload until specified pinion torque is obtained. If bearing preload is exceeded before torque specification is reached, replace collapsible spacer.
  6. Install new pinion nut and repeat procedures. Do not loosen pinion nut to reduce pinion bearing preload.
