  1. Raise and support the vehicle. Clean any dirt from around the differential fill plug. Remove the fill plug, lubricant tag, and washer from the differential. Check the differential fluid level, it should be even with the bottom of the fill plug hole to no lower than 0.25" (6 mm) below the opening.
  2. Add new fluid if necessary. Fill with synthetic axle lubricant (1237826). If necessary, add enough limited-slip differential lubricant additive (1052358), or equivalent to maintain the original ratio of 1.69 qt. (1.6 L) of axle lubricant to 4.0 oz. (118 ml) of limited-slip additive.
  3. Install the fill plug, lubricant tag, and washer to the differential. Tighten the differential fill plug to specification. See TORQUE SPECIFICATIONS . Lower the vehicle.
