The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Dealer World Message # VSE20060324

A limited number of early-built 2007 (GMT900) Silverado and Sierra Extended Cab Trucks do not have mounting provisions to allow for installation of the Silverado / Sierra Accessories Tubular Assist Steps. The new rocker panels went into production on 10/16/06. However, vehicles were built prior to this change being implemented. VIN breakpoint information does not exist relative to incorporating the new rocker panels in vehicle assembly

Therefore, a visual inspection of the truck will be required to verify that the vehicle has the required mounting holes and tabs prior to attempting to install assist steps.

There are four sets of mounting holes and tabs per side. If the truck does not have tabs with holes in them on the very bottom of the rocker panel, mounting provisions do not exist on that vehicle.

Note:  You can NOT drill holes into the rocker panel to install these tube steps because the tabs are required.
