LEVEL CHECK

The drive axle fluid level is checked from underneath the truck.

  1. Clean the dirt and grease away from the area of the filler (top) plug.
  2. Remove the filler plug. The lubricant level should be even with the bottom of the filler plug hole.
  3. If lubricant is required, use only the specified type. It will probably have to be pumped in through the filler hole. Hypoid SAE 90 lubricant usually does not pour very well.
