- Thoroughly wash the axle shift parts and housing cover, and allow them to air dry.
- 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.
- 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.
- 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.
Important: Also do the appropriate procedure under the heading “All Axle Models.”
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).
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.
