Pinion Flange & Oil Seal

  1. Raise vehicle and remove pinion flange bolts. Position drive shaft out of way. Count number of exposed threads and scribe a mark on pinion stem, nut, and pinion flange for reassembly reference.
  2. Use Companion Flange Holder Set (J-8614-01) to hold flange. Remove pinion nut and pinion flange from pinion. Using care not to damage machined surfaces, pry oil seal from bore. Clean area thoroughly. Pack cavity between seal lips with high melting point bearing lubricant.
  3. Place new seal into bore. Use Pinion Oil Seal Installer (J-24384) to drive seal in until it bottoms against inner shoulder. Install pinion flange and pinion nut to the scribe mark to ensure proper alignment. Install drive shaft. Tighten flange bolts to specification. See TORQUE SPECIFICATIONS  table.
