Dana Spicer Axle
Notice: Failure to keep the rear axle filled to the proper level with the recommended lubricant can result in rear axle damage.
- Park the vehicle on level ground, apply the parking brakes, and chock the tires.
- If the vehicle has just been driven, allow a few minutes for the lubricant to settle.
- Clean the oil fill plug and area surrounding it, then remove
the plug from the fill hole (see Fig.), or from the standpipe (if so equipped) installed in the fill hole.

Table 1, Dana Spicer Drive Axle Recommended Lubricant
- Lubricant should be level with the bottom of the fill hole (see Fig.), or with the top of the standpipe opening. If low, check the axle for oil leaks, and correct as needed. Add lubricant as required. See Table. for recommended drive axle lubricants.
- Install and tighten the fill plug 40 to 60 lbf·ft (54 to 81 N·m).
- For a two-speed axle with a shift unit, check the lubricant level of the shift unit; see elsewhere in this maintenance operation for the shift unit lubricant level inspection procedure.
- Remove the chocks from the tires.
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 (see Fig.), or the top of the standpipe opening.
Important: Axle housing breathers (see Fig.) must remain clean and unclogged. Always check the axle breather whenever checking lubricant level. Ensure that it is open and unclogged. Check the breather more frequently under adverse operating conditions. If the breather is plugged or damaged, clean or replace it as needed.
