- Pry the seal from the case using a suitable prybar.
- Install the new pinion seal using a seal installer ST30720000 or equivalent.
- Install the pinion flange and nut. While holding the pinion flange using special tool J34311 or equivalent, tighten the nut to 123-145 ft. lbs. (167-196 Nm).
- Using an inch lbs. torque wrench, turn the drive pinion in both directions, several times, and measure bearing preload. The preload should be 6.5-13.5 inch lbs. (0.74-1.52 Nm).
In order to accurately check bearing preload, both rear halfshafts must be disconnected from rear axle housing.
