Removal Procedure

WARNING: This page is about a different car, the 2019 GMC Savana 3500, 2019 GMC Savana 2500, 2019 Chevrolet Express 3500, and 2019 Chevrolet Express 2500. However, it is still accessible from the selected car via links, so may be relevant.
    WARNING:

    Provide additional support when a vehicle is on a hoist in the following ways:

    • Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off. 
    • Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off. 

    Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.

    WARNING:

    When you remove the body cushions, do NOT separate the frame from the body more than is necessary. Possible personal injury and damage to multiple parts may result if you do not follow the guides outlined below:

    • Fuel tank filler hose - Do not stretch the hose excessively.
    • Tail/Turn signal lamp wiring/rear lamps junction block - Leave slack in the wires.
