Fig. Fig. 1: The front and rear filler plugs on most of your trucks are located in these areas shown

  1. With the truck parked on a level surface, remove the filler plug from the back of the differential.
  2.  

The plug on the bottom is the drain plug.

  1. If the oil begins to trickle out of the hole, there is enough. Otherwise, carefully insert your finger (watch out for sharp threads) into the hole and check to see if the oil is up to the bottom edge of the filler hole.

DRAIN AND REFILL



Front

See Figures 5, 6 and 7

The gear oil in the front axle should be changed at least every 25,000-30,000 miles (40,000-48,000 km) or immediately if driven in deep water.

  1. Park the vehicle on a level surface. Set the parking brake.
  2.  
  3. Clean the area around the drain plug.
  4.  
  5. Remove the filler (upper) plug. Place a container which is large enough to catch all of the differential oil under the drain plug.
  6.
