Pinion Flange & Oil Seal: Installation

WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 GMC Sonoma, 2002 GMC Sierra, and 2002 GMC Savana Special. However, it is still accessible from the selected car via links, so may be relevant.
  1. Thoroughly clean contact area. Inspect pinion flange oil seal surface and drive splines. Replace pinion flange if damaged. Lubricate inside diameter of seal. Place pinion seal into housing bore.
  2. Using Seal Installer (J-33782) for 7.6" and 8.0" ring gear or (J-22388) for 8.6" and 9.5" ring gear, install pinion seal. Apply a coat of high-temperature lubricant to pinion seal lip.
  3. CAUTION: Do not hammer flange onto pinion shaft to install. Ring gear and pinion will be damaged.
  4. Align pinion flange marks with marks on pinion. Install pinion flange. Install washer and NEW nut to pinion. Tighten nut snug, taking note of scribe marks and number of exposed threads. Measure pinion preload. Using pinion flange holder and remover, tighten nut in small increments. Rotate flange after each increment. Tighten pinion nut until rotational torque is 3-5 INCH lbs. (0.40-0.57 N.m) greater than rotational torque prior to yoke removal. Install drive shaft. Add lubricant as needed. See LUBRICATION .
