Rear Axle Lubricant Level Inspection 8.6 Inch Axle

Note: All axle assemblies are filled by volume of fluid during production. They are not filled to reach a certain level. When checking the fluid level on any axle, variations in the readings can be caused by factory fill differences between the minimum and the maximum fluid volume. Also, if a vehicle has just been driven before checking the fluid level, it may appear lower than normal because the fluid has traveled out along the axle tubes and has not drained back to the sump area. Therefore, a reading taken five minutes after the vehicle has been driven will appear to have a lower fluid level than a vehicle that has been stationary for an hour or two. Remember that the rear axle assembly must be supported to get a true reading.

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Make sure the vehicle is level.
3. Inspect the rear axle for leaks. Repair as necessary.
4. Clean the area around the rear axle fill plug.



5. Remove the rear axle fill plug.
6. Inspect the lubricant level.

Specification
The lubricant level should be between 0-10 mm (0-0.4 in) below the fill plug opening.

7. If the fluid level is low, add lubricant until the level is within specifications. Use the proper fluid. Refer to Adhesives, Fluids, Lubricants, and Sealers.

Caution: Refer to Fastener Caution in the Preface section.

8. Install the rear axle fill plug and tighten to 33 N·m (24 lb ft).
9. Lower the vehicle.

Rear Axle Lubricant Level Inspection 9.5 Inch LD Axle

Note: All axle assemblies are filled by volume of fluid during production. They are not filled to reach a certain level. When checking the fluid level on any axle, variations in the readings can be caused by factory fill differences between the minimum and the maximum fluid volume. Also, if a vehicle has just been driven before checking the fluid level, it may appear lower than normal because the fluid has traveled out along the axle tubes and has not drained back to the sump area. Therefore, a reading taken five minutes after the vehicle has been driven will appear to have a lower fluid level than a vehicle that has been stationary for an hour or two. Remember that the rear axle assembly must be supported to get a true reading.

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Ensure the vehicle is level.
3. Inspect the rear axle for leaks. Repair as necessary.
4. Clean the area around the rear axle fill plug.



5. Remove the rear axle fill plug.
6. Fabricate a dipstick from a pipe cleaner of similar item. Form the pipe cleaner into the shape of an "L".

Note: Ensure the pipe cleaner is resting on the bottom threads of the fill hole.

7. Insert the pipe cleaner into the fill plug opening with the stem of the "L" facing down.
8. Inspect the lubricant level.

Specification
The lubricant level should be between 15-40 mm (0.6-1.6 in) below the fill plug opening.

9. If the level is low, add lubricant until the level is within specifications. Use the proper fluid. Refer to Adhesives, Fluids, Lubricants, and Sealers.

Caution: Refer to Fastener Caution in the Preface section.

10. Install the rear axle fill plug and tighten to 33 N·m (24 lb ft).
11. Lower the vehicle.
