Removal Procedure

Important: The seals used in the differential carrier assembly have built in tabs that are used to retain the position of the differential side bearing adjusters. When removing the seal, do not twist or rotate the seal or the preload on the differential case side bearings may be affected.

  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Drain the lubricant from the differential carrier assembly. Refer to Lubricant Change .
  3. Remove the left wheel drive shaft. Refer to Wheel Drive Shaft Replacement in Wheel Drive Shafts.

Installation Procedure

Important: The seals used in the differential carrier assembly have built in tabs that are used to retain the position of the differential side bearing adjusters. When installing the seal, it is not necessary to align the tabs to the slots on the differential side bearing adjuster. Two of the tabs on the seal will automatically align themselves with the slots on the differential side bearing adjuster when the seal is installed.
