  2. Thoroughly wash the axle shift parts and housing cover, and allow them to air dry.
  3. Install the housing cover and a new cover gasket. Tighten the housing cover capscrews 90 to 110 lbf·in (1020 to 1240 N·cm), then remove the oil fill plug from the cover.
    Commercially available automatic transmission fluid may be used in place of SAE 10 engine oil. Automatic transmission fluid can be used for all temperatures; do not mix it with kerosene. To prevent component damage, do not mix engine oil and automatic transmission fluid.

    4. Important: When the ambient temperature is above 0°F (–18°C), use SAE 10 heavy-duty engine oil, API service classification SD (sulfated ash content must not exceed 1.85%). When the ambient temperature is below 0°F (–18°C), use one part kerosene to three parts SAE 10 heavy-duty engine oil, API service classification SD (sulfated ash content must not exceed 1.85%). This cold-weather mixture can be safely used up to 32°F (0°C).

  4. Using the recommended lubricant, fill the shift unit housing through the oil fill hole until the lubricant is level with the bottom of the opening.
  5. Coat the threads of the fill plug with a small amount of Loctite® 242, or equivalent sealant. Install the fill plug finger-tight in the rear axle shift unit housing. Using a wrench, tighten it an additional 1-1/2 turns.
