Replacement of rear axle drive pinion seal only involves removal and installation of pinion nut and rear axle universal joint flange.
1. CAUTION: This operation disturbs the pinion bearing preload. This preload must be carefully reset when assembling.
Raise the vehicle and install safety stands. Remove rear wheels.
2. Draw marks on the driveshaft centering socket yoke and rear axle universal joint flange for proper positioning of the driveshaft during assembly.
Disconnect the driveshaft from the rear axle universal joint flange. Remove the driveshaft from the transmission extension housing. Install an oil
seal replacer tool in the transmission extension housing to prevent oil leakage.
3. Install a Nm (inch lbs.) torque wrench on the pinion nut. Record torque required to maintain rotation of the pinion through several revolutions.
