Replacement of the Weld Nut and Reinforcement
Missing Weld Nut and/or Rear Seat Reinforcement at the C-Pillar1. Remove D-Ring and the interior trim panel to expose the suspect anchor point.
2. Determine if only the weld nut or the entire weld nut and reinforcement and weld nut are missing. If it is determined that the reinforcement is missing, this procedure cannot be done and the body side must be removed and replaced to complete the necessary repair. To install a missing weld nut only, proceed to step 3.
3. Obtain a 7/16-in. weld nut and a standard washer.
4. Drill out two (2) 8 mm (5/16-in.) diameter holes adjacent to clearance hole.
5. Obtain a length of copper welding wire and feed through clearance hole in door frame opening until it becomes visible at the access hole.
6. Pull the wire through so that it may be secured to the weld nut and washer.
7. Pull wire back up to the weld nut clearance hole.
8. Hold weld nut securely in place and using Rotunda MIG Wire Feed Welder 106-00053 or equivalent, plug weld the nut in place at the two (2) 8 mm (5/16-in.) diameter holes previously drilled.
9. Metal finish as required.
10. Verity the nut is securely in place by performing certification test.
Missing Weld Nut and/or Front Seat Reinforcement at the Upper B-Pillar
1. Remove the D-Ring and the interior trim panel to expose the suspect anchor point.
2. Determine if the weld nut only or the weld nut and reinforcement and weld nut are missing. If it is determined that the reinforcement is missing, this procedure cannot be done and the body side must be scrapped to complete the necessary repair. To install a missing weld nut only, proceed to Step 3.

1. Remove the interior trim panel to expose the suspect anchor point.
2. Obtain a 7/16-in. weld nut.
3. Drill two (2) 8 mm (5/16-in.) diameter holes adjacent to the clearance hole.
4. Align weld nut with the clearance hole using a piece of round stock.
5. Secure in place and using Rotunda MIG Wire Feed Welder 106-00053 or equivalent, plug weld at the two (2) 8 mm (5/16-in.) diameter holes previously drilled.
6. Metal finish as required.
