Removal Procedure

2008 Chevrolet Chevy Express G2500, Van Cargo, 6.6 6SECTION Removal Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to the coil assembly.

Verify the following before removing the inflatable restraint steering wheel module coil:
- The wheels on the vehicle are straight ahead.
- That anti-rotation pin J 42640 is installed or the ignition and start switch is in the LOCK position.
Remove the steering wheel. Refer to Steering Wheel Replacement .
Remove the steering column shroud. Refer to Steering Column Shroud Replacement .
Disconnect any electrical connectors as needed.
