Carrier Bearing End Play Adjustments

NOTE: This adjustment is not required on Cherokee 8 1/4" rear axle.
  1. Place bearing cup over each carrier bearing. Install carrier assembly (without ring gear) into axle housing. Install a .142" (3.60 mm) shim on outer side of each carrier bearing cup on Cherokee, Comanche and Wrangler axles. On Grand Wagoneer axles, install a shim (which allows some side play) on each side of carrier bearing cup.
  2. Install bearing caps and tighten bolts finger tight. Mount dial indicator to housing. See Figure . Using a pry bar between shims and housing, move assembly to one side. Zero dial indicator. Pry assembly to opposite side. Record indicator reading. DO NOT  zero or read indicator while prying.
  3. Indicator reading (when divided by 2; one for each side) is the thickness of shims required. Shims are available in .002" (.050 mm) increments.
  4. When all side play is eliminated, check drive gear face of carrier for runout by rotating carrier and reading dial indicator. Runout should not exceed .002" (.050 mm). Remove carrier from housing and retain shims. See Figure .
