OEM Linking Pin: GM Adhesively Bonded Joint Repair

Posted on 21 February 2024 Print

As part of the I-CAR Repairability Technical Support (RTS) OEM linking pin activity, we are helping to connect the collision repair industry to the vehicle makers. We‘ve had technical inquiries that asked for clarification on repairing parts or assemblies with adhesively bonded joints on GM vehicles.

Many GM body repair manuals (BRM) procedures specify factory adhesive and the use of adhesive for replacement. We reached out to our contact at GM for clarification on repairing these areas, specifically when it comes to straightening and pulling.

Per our contact at GM: "Although no specific information has been published, pulling/rough pulling in conjunction with proper anchoring/fixturing and 3D measuring is acceptable on components that will require replacement during the repair process and/or if mild steel type is present and repairability is allowed. If deformation exists at weld flange locations that have Impact Resistant Adhesive present the damaged component should be replaced."
