Removal Procedure

Note. The front wheelhouse panel is cast aluminum and it is rivet bonded to the front lower frame rail (Ultra High Strength Steel) and hinge pillar upper extensions (Dual Phase Steel). The front wheelhouse is serviced as a complete assembly that includes the hinge pillar upper extension, which is rivet bonded to the front wheelhouse panel.

Note. This procedure describes how to replace the complete front wheelhouse assembly, using recommended adhesive and rivets to attach the assembly to the front lower frame rail. The assembly requires welding at the cowl on the upper hinge pillar extension.

Note. Partial replacement of the front wheelhouse assembly can be done by replacing only the front wheelhouse panel (cast aluminum). The front wheelhouse panel will need to be separated from the complete wheelhouse service assembly and replaced using adhesive and rivets.

Aluminum Panel Bonding

This information is intended to provide general guidelines for adhesive bonding of aluminum panels. Panel bonding of aluminum is only recommended when the panel is originally bonded to the vehicle.

The adhesives listed in this document are known to meet the General Motors specifications and requirements for bonding of aluminum body panels.

Bonding procedures in general are applicable only at factory joints.

The use of adhesive to section aluminum panels is not recommended by General Motors.

Rivets, or other mechanical fasteners, may be used in combination with adhesive bonding of aluminum panels. The specified rivets, or fasteners, should be used with adhesive, when replacing the original panel.

Two types of adhesives are listed here. Impact Resistant Adhesive is used in joints in frame rail assemblies and strut tower assemblies and other body structure joints that have critical strength requirements. The factory applied Impact Resistant Adhesive is purple in color when cured. The only adhesive available for servicing these joints is Dow Betamate 2098. The other bonding adhesives are non-impact resistant, offer a lower strength rating and can be used in all other joints that are not originally made with Impact Resistant Adhesive

Note. Always follow the adhesive manufacturer's instructions for application, handling, and curing for the specific product.

Adhesives currently meeting the performance requirements include the adhesive products listed below meet these guidelines

The scope of this specification is intended to provide the performance guidelines of structural adhesive systems used to repair (metallic) automotive bodies in the aftermarket. These types of adhesives are intended for use when bonding replacement body panels as an option to welding as the attachment means. GM information outlines the use of room temperature cure acrylic adhesives that contain glass bead technology.

Bonding procedures in general are applicable only to a factory seams type approach.

Sectioning or partial paneling of full panels is not supported by General Motors unless specifically documented in a Service Bulletin or Manual.

Applicable components for this technology are EXTERIOR PANELS ONLY, including door skins, tail panels, roof outer panels and quarter panels.
