The standard front and rear axle differentials use SAE 80W/90 gear oil. Either is acceptable for use in the differential housing. Powr-Lok® differentials use only Jeep Powr-Lok® Lubricant or its equivalent. In Trac-Lok® axles, use any limited slip gear oil meeting SAE 75W/90, 80W/90 or 85W/90 specifications. Check the level of the oil in the differential housing every 5,000 miles under normal driving conditions and every 3,000 miles if the vehicle is used in severe driving conditions. The level should be up to the filler hole. When you remove the filler plug, the oil should start to run out. If it does not, replenish the supply until it does.

The lubricant should be changed every 30,000 miles. If running in deep water, change the lubricant daily.

FLUID CHANGE



The lubricant in the front and rear axle differentials should be checked about every 5,000 miles or sooner, if the vehicle is operated under severe conditions, and should be changed every 12,000 miles. Follow the procedure given below for changing the lubricant in the front and rear axle differentials:

  1. Remove the axle differential housing cover and allow the lubricant to drain out into a proper container.
  2.  
  3. Install the differential housing cover and a new gasket.
