WELD NUT REPAIR - MISSING WELD NUT
CAUTION: Installing a J-nut in place of a weld nut is not a recommended repair.
NOTE: C-pillar repair shown, others similar.
1. Depower the system.
2. Remove the component from where the weld nut is to be repaired.
3. Drill three equally spaced 5/64 in (1.75 mm) holes in close proximity to where the weld nut face will be plug welded back to the sheet metal.
4. Obtain the appropriate 6 mm (0.24 in) or 8 mm (0.32 in) weld nut.
5. Obtain the appropriate 6 mm (0.24 in) by 1.0 or 8 mm (0.32 in) by 1.25 grounding screw (self-tapping).
6. Set up for the positioning of the weld nut.
1 Route a sufficient length of wire through the weld nut clearance hole and back out an adjacent access hole.
2 Position a weld nut, shoulder end up, onto the wire.
3 Position a flat washer onto the wire and secure it so it cannot be pulled off.
7. Plug weld the weld nut into position.
1 Pull the welding wire back through the clearance hole, allowing the weld nut and flat washer to follow the welding wire through and stop against the sheet metal.
2 Make sure the weld nut shoulder is aligned through the clearance hole in the sheet metal.
3 With the weld nut firmly held in position, plug weld the weld nut at the three holes drilled previously.
8. Metal finish as required.
9. Verify the nut is securely in place.
10. Install the component with the previously obtained screw.
11. Tighten the attaching screws to specification.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
