clean before checking the oil. Do not use a pres-

sure washer to clean the hub/plug area. The plug

has a vent and this can contaminate the oil with

water.

1. Park the vehicle on a level surface, shut down

the engine and set the parking brakes. Chock

the tires.

2. Inspect the axle hub cap and vent plug for evi-

dence of excessive leakage.

3. Wipe the hub cap and vent plug clean with a rag.

4. Remove the vent plug and check the oil for evi-

dence of water contamination.

If there is evidence of water contaminated oil in

the hub, disassemble the effected axle end,

clean, inspect, and reassemble the axle end. For

instructions, refer to Group 33 of the vehicle’s

Workshop Manual.

If there is evidence of excessive leakage, re-

move the damaged part and replace it with a

new part.

5. Check the oil level in the hub, and ﬁll the hub

with new approved oil as needed.
