When to Check Lubricant
Refer to Maintenance Schedule 0 384 to determine when to check the lubricant.
To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the fill plug (1) hole, located on the transfer case, some lubricant will need to be added. Add enough lubricant to raise the level to the bottom of the fill plug (1) hole. Use care not to overtighten the plug.
When to Change Lubricant
Refer to Maintenance Schedule 0 384 to determine how often to change the lubricant.
What to Use
Refer to Recommended Fluids and Lubricants 0 393 to determine what kind of lubricant to use.
When to Check Lubricant
It is not necessary to regularly check the front axle fluid unless a leak is suspected or an unusual noise is heard. A fluid loss could indicate a problem. Have it inspected and repaired. This service can be complex. See your dealer.
Do not directly power wash the transfer case and/or front/rear axle output seals. High pressure water can overcome the seals and contaminate the fluid. Contaminated fluid will decrease the life of the transfer case and/or drive axles and should be replaced.
