Seat Belt: Service and Repair
Service Procedures
Post Collision Inspection
1. Before installing the new safety belt assembly, the safety belt attaching areas must be inspected for damage and distortion. If the attaching points
are damaged and distorted, the sheet metal must be reworked back to its original shape and structural integrity.
WARNING: All safety belt assemblies including retractors, buckles, front seat belt buckle support assemblies (slide bar), shoulder belt
height adjusters, if so equipped, child safety seat tether attachments, and attaching hardware should be inspected after any collision. All
belt assemblies should be replaced unless a qualified technician finds the assemblies show no damage and operate properly. Belt
assemblies not in use during a collision should also be inspected and replaced if either damage or improper operation is noted.
NOTE: Safety belt assemblies should be periodically inspected to make sure they have not become damaged and that they remain in proper
operating condition, particularly if they have been subjected to severe stress.
2. Install the new safety belt(s) using the appropriate instructions. Perform the Component Test.
Replacement of the Weld Nut and Reinforcement
1. Remove 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 the B- or C- or D-pillar safety belt anchor nuts or
reinforcements are stripped or missing, they should be replaced with a new nut or reinforcement. To install a missing weld nut only, proceed to
Step 3.
3. Obtain a M12 weld nut and a standard washer.
4. Drill out two 8 mm (5/16 in) diameter holes adjacent to the 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 the wire back up to the weld nut clearance hole.
8. Hold the weld nut securely in place. Use the MIG Wire Feed Welder to plug weld the nut in place at the two 8 mm (5/16 in) diameter holes
previously drilled.
9. Metal finish as required.
10. Verify the nut is securely in place.
