    IMPORTANT: Replace the carrier if pinion gear clearance is out of specification. The pinion gears are permanently assembled to the carrier and are not serviced individually.
  1. Measure the pinion gear end play for proper clearance. Use a feeler gage. The clearance should be 0.24-0.69 mm (0.01-0.027 in).
  2. Inspect the reaction internal gear and the input carrier assembly for damage or excessive wear. Specifically inspect the condition of the pinion gears, the washers, and the thrust bearings.
  3. Clean and dry each of the components.
