Part 4 of 4
Item 16: Differential Bearing Shim Assembly Note
1. Establish differential bearing preload.
^ To establish bearing preload, use the special tool to increase both the left and right shim sizes by the specification shown.
^ Use the special tool to make sure the differential bearing shims are fully seated.
Item 7: Drive Pinion Collapsible Spacer Assembly Note
1. CAUTION: Make sure the splines on the drive pinion gear stem are free of burrs. If burrs are evident, remove them using a fine crocus cloth.
Place a new differential drive pinion collapsible spacer on the drive pinion gear stem against the pinion stem shoulder.
2. Install the drive pinion gear with the differential drive pinion collapsible spacer in the differential housing.
Item 4: Rear Pinion Oil Seat Assembly Note
1. CAUTION: Installation without the correct tool can result in early seal failure.
CAUTION: If the seal becomes misaligned during installation, remove it and install a new one.
NOTE: Coat the rear axle drive pinion seal lips with grease.
Using the special tool, install the new rear axle drive pinion seal.
Item 2: Rear Axle Pinion Flange Assembly Note
1. NOTE: Disregard the index marks if installing a new rear axle pinion flange.
Position the rear axle pinion flange.
1 Lubricate the rear axle pinion flange splines. 2 Position the rear axle pinion flange.
2. Using the special tool, install the rear axle pinion flange.
Item 1: Pinion Nut Assembly Note
1. CAUTION: Do not, under any circumstance, loosen the nut to reduce preload. If it is necessary to reduce preload, install a new collapsible spacer and nut.
CAUTION: Remove the special tool while taking preload readings with the Nm (inch-pound) torque wrench.
Use the special tool to hold the pinion flange while tightening the nut.
^ Rotate the pinion occasionally to make sure the differential pinion bearings seat correctly. Take frequent differential pinion bearing preload readings by rotating the pinion with a Nm (inch-pound) torque wrench.
2. Tighten the nut to set the preload.
