The California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty. The California Air Resources Board has also determined that the failure to perform this maintenance item will not limit the recall liability prior to the completion of the vehicle useful life. GM, however, urges that all recommended maintenance be recorded.

Drive Axle Service:

    • The Locking Differential
        Drain the fluid and refill the fluid at the first engine oil change. At subsequent oil changes, inspect the fluid level and add fluid as necessary. Drain the fluid and refill the fluid every 25 000 km (15,000 miles) if the vehicle is performing either of the following actions:
       - Driving in dusty areas
       - Towing a trailer
    • The Standard Differential
        Inspect the fluid level and add fluid as necessary at every oil change. Drain the fluid and refill the fluid every 25 000 km (15,000 miles) if the vehicle is performing either of the following actions:
       - Driving in dusty areas
       - Towing a trailer
    • Heavy-duty or off-road use may require more frequent lubrication.
