Carrier & Pinion Shaft

  1. Install front and rear bearing outer races into carrier. Press rear drive pinion bearing onto drive pinion with depth shim under bearing. Install drive pinion into carrier. Install front bearing.
    NOTE: Drive pinion preload is set in 2 stages. Initial adjustment is made without spacer, oil slinger or oil seal installed. Final adjustment is made after differential case is installed and ring and pinion backlash have been set.
  2. Install drive pinion flange and lightly grease threads of pinion flange nut. Install flange nut and adjust drive pinion preload by slowly tightening nut. Measure preload with torque wrench. Preload range is 10-16 INCH lbs. (1.0-1.6 N.m) for new bearings and 5.2-8.7 INCH lbs. (.6-1.0 N.m) for used bearings.
  3. Install differential case and adjust ring gear-to-drive pinion backlash. Remove drive pinion flange and front bearing. Install new bearing spacer with large end toward differential. Install front bearing, oil slinger, and oil seal. Install drive pinion flange and tighten pinion nut.
  4. Check total differential preload and adjust if necessary. Check gear tooth pattern. See GEAR TOOTH CONTACT PATTERNS article in GENERAL INFORMATION section. Check that drive pinion flange runout do not exceed specification. Stake drive pinion nut. Drive side gear shaft oil seal into carrier until flush.
  5. Measure side gear runout at flange. Install differential carrier cover with new gasket and tighten bolts.
