Pinion Bearing Preload

  1. Place pre-selected 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 oil seal and hold firmly in place.
  3. From rear of axle housing, insert pinion shaft into flange. Install a NEW  pinion nut on pinion shaft and gradually tighten pinion nut while holding flange.
    NOTE: If installing a NEW  companion flange, disregard scribed mark on pinion shaft.
  4. Check bearing preload often. As soon as preload is measured, turn pinion shaft in both directions several times to seat bearings. Hold companion flange with Companion Flange Holder (T78P-4851-A) while tightening nut.
  5. Tighten pinion nut and continue to measure pinion bearing preload until the specified pinion torque is obtained. See DIFFERENTIAL SPECIFICATIONS  . If bearing preload is exceeded before torque specification is reached, replace collapsible spacer. Install NEW  pinion nut and repeat procedures. DO NOT  loosen pinion nut to reduce pinion bearing preload.
