Note: When adding to or checking the oil level, make certain the hub cap and plug are clean before removing the plug; this will minimize the possibility of dirt and road grime entering the assembly.

    Notice: Failure to keep the rear axle filled to the proper level with the recommended lubricant can result in rear axle damage.

  1. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
  2. If the vehicle has just been driven, allow a few minutes for the lubricant to settle.
  3. Clean the oil fill plug and the area surrounding it; see Fig.. Remove the plug from the fill hole (or standpipe, if installed in the oil fill hole).

    4. Important: A lubricant level close enough to be seen or touched is not sufficient. It must be level with the bottom of the fill hole, or the top of the standpipe opening.

  4. Check that the lubricant is level with the bottom of the fill hole, or with the top of the standpipe opening. See Fig.. If low, check for oil leaks, and correct as needed. Add oil to the level of the fill plug, using the lubricant recommended in Table..

    • Correct (lube level at bottom of fill hole)

    • Incorrect (lube level below fill hole)

    1. Install and tighten the fill plug 40 to 60 lbf·ft (54 to 81 N·m).

      2. Important: Always check the axle breather whenever checking the lubricant level. Check the breather more frequently under adverse operating conditions.

    2. Check the axle housing breather. Make sure that it is unclogged and free from corrosion. See Fig.. If the breather is plugged or damaged, clean or replace it as needed.
