  1. Disconnect the (-) battery terminal.
  2. Remove the rear driveshaft.

(Refer to Rear Driveshaft Assembly - "Rear Driveshaft")

  1. Remove the propeller shaft.

(Refer to Propeller Shaft Assembly - "Propeller Shaft")

  1. Remove the coupling assembly.

(Refer to All Wheel Drive (AWD) System - "Direct Electro Hydraulic Actuator Coupling")

  1. Install a jack oil the lower part of the differential.
  2. Remove the differential carrier assembly (A) after loosening the mounting bolts.

Tightening torque : 68.6 - 88.2 N m (7.0 - 9.0 kgf-m, 50.6 - 65.0 lb ft)

  1. Remove the differential carrier bracket (A) after loosening the mounting bolts



  1. After clearing, check for damage parts or abrasion. Follow the below method, if any are noticed.

  1. Check the tooth contact pattern.



1) Tooth contact pattern is a method for judging the result of the adjustmentof drive pinion height and final drive gear backlash. The adjustment of drivepinion height and final drive gear backlash should be repeated until the toothcontact patterns are similar to the standard tooth contact pattern.

2) When you cannot obtain a correct pattern, the drive gear and drive pinionhave exceeded their limits.

Both gears should be replaced as a set.
