Front Differential
The front differential oil should be changed every 100 hours If the
vehicle is used in wet conditions, the oil should be checked more fre-
quently. If the oil has a milky appearance, it should be changed as
soon as possible. Failure to properly maintain this area can result in
premature wear or possible failure of the front differential compo-
nents.
Oil Check
1. With the vehicle on a level surface, remove the fill plug and check
the lubricant level. Oil should be filled until it overflows from the
fill plug.
2. Replace the fill plug and tighten.
Oil Change
1. Support the vehicle securely with a jack stand.
2. Remove the front tire on the driver’s side.
3. Remove the fill plug.
4. Remove the drain plug located on the bottom right-hand side and
drain the oil into a drain pan. Discard the used oil properly.
5. Clean and reinstall the drain plug.
6. Add Mobil 424 oil to 3/4” below the threads of the fill plug hole.
7. Reinstall the fill plug and tighten. Check for leaks.
