  1. Put required amount of shims and baffle (if used) in inner bearing bore. See DRIVE PINION DEPTH  . Use Rear Pinion Bearing Race Installer (J-39707) and Handle (J-39708) to install drive pinion inner bearing race into drive axle housing. Ensure race is fully seated on shims.
  2. Use Rear Pinion Bearing Cone Installer (J-5590) to install drive pinion outer bearing race into drive axle housing. Use pinion bearing installer to install inner bearing and baffle (if used) onto drive pinion.
  3. Install drive pinion into drive axle housing. Install outer drive pinion bearing and slinger (if used). Install preload shims. Lubricate and install oil seal.
  4. Install drive pinion yoke. Install washer and NEW drive pinion nut. Using Pinion Yoke Holder/Remover (J-8614-01) to hold pinion, tighten drive pinion nut to specification. See TORQUE SPECIFICATIONS  . Tighten nut until all end play is removed. Rotate drive pinion several times to seat bearings. Once there is no end play, check preload torque.
    5. NOTE: Pinion preload should be at or less than 35 INCH lbs. (4 N.m) on new bearings, or 10 INCH lbs. (1.1 N.m) on old bearings.
  5. Check preload by rotating pinion with INCH-lb. torque wrench. See Figure . If necessary, remove small diameter shims to increase preload, or add shims to decrease preload.
