Pinion Bearing Preload
- Apply oil to seal. Install seal, yoke, washer and original nut. Tighten pinion nut only enough to remove bearing end play. Remove original nut, washer and yoke and install NEW collapsible spacer. Reassemble components, including oil slinger (if equipped).
- Place an INCH-lb. torque wrench on pinion nut. Rotate pinion, and note rotating torque. Hold yoke using Yoke Support Wrench (C-3281). Tighten pinion nut until specified preload torque is obtained. See PINION BEARING PRELOAD SPECIFICATIONS table. Pinion nut torque should equal or exceed specification. See TORQUE SPECIFICATIONS table. If pinion nut torque does not equal or exceed specification, replace collapsible spacer.
CAUTION:
DO NOT reuse collapsible spacer.
CAUTION:
DO NOT overtighten pinion nut. If preload torque is exceeded, collapsible spacer must be replaced and preload reset.
