They should operate freely with no binding. 10.Check the adjustment of the temperature cable as follows: A. Rotate the temperature control knob to the full COLD position (i.e., fully counterclockwise) and confirm the air mix door is fully seated (sealed) in the down position, then B. Rotate the temperature control knob to the full HOT position (i.e., fully clockwise) and confirm the air mix door is fully seated (sealed) in the up position. If the air mix door does not fully seat (seal) in either the full HOT or full COLD position: • Adjust the temperature control cable, with the temperature control knob in the full hot position, using the clip at the heater unit (see Figure 7) 11.Re-install the trim pieces removed in step 1.

Hold the nut in position while installing the hex screw. Tighten the hex-head screw until contact is made with the Step Plate 7. Insert a suitable dowel bar in the hole of the nut. Tighten the forcing screw to force the differential side gear away from the differential pinion gears. The dowel bar is used to keep the nut from turning when the forcing screw is tightened. 8. WARNING: Keep fingers/hands away from pinion gears when rotating the differential case with the differential rotating tool. NOTE: Differential pinion thrust washers cannot be removed independently of the differential pinion gears and so must be removed simultaneously with the differential pinion gears. Insert the special tool in the pinion shaft bore and turn the differential case to “walk” the differential pinion gears and differential pinion thrust washers out to the differential case windows. 9. Remove the differential pinion gears and differential pinion thrust washers. 10. Remove the differential side gears and differential clutch packs and tag them RIGHT and LEFT with the shim. CAUTION: When separating the clutch plates and clutch discs, note the sequence in which they are disassembled. They must be reassembled in the same sequence. CAUTION: Do not use acids or solvents when cleaning the differential clutch pack. Wipe components with a clean, lint-free cloth only. Separate the differential clutch discs and clutch plates for cleaning and inspection. Refer to the disassembled view of the limited slip differential case in the Description and Operation portion of this section.
