Tools and Materials

Step-by-Step Procedure

Step 1: Prepare the Vehicle

Thoroughly clean the area around the damaged cab corners. Remove any dirt, rust, or loose paint using a wire brush or sandpaper. This will ensure proper adhesion of the replacement cab corners.

Step 2: Remove the Old Cab Corners

Using a drill or screwdriver, carefully remove the old cab corners. Be cautious not to damage the surrounding areas while removing the old parts.

Step 3: Test Fit the Replacement Cab Corners

Place the replacement cab corners against the vehicle to check the fit. Make any necessary adjustments or modifications to ensure a proper fit before proceeding.

Step 4: Apply Adhesive/Sealant

Apply a suitable adhesive or sealant to the backside of the replacement cab corners. Make sure to use a product specifically designed for automotive applications. The adhesive will create a strong bond between the cab corners and the vehicle body.

Step 5: Install the Replacement Cab Corners

Position the replacement cab corners onto the vehicle, aligning them properly. Use clamps to hold them in place while the adhesive sets. Follow the manufacturer's instructions for the recommended curing time of the adhesive.

Step 6: Finishing Touches

Once the adhesive has fully cured, remove the clamps and ensure that the replacement cab corners are securely attached to the vehicle. If needed, apply touch-up paint or protective coating to match the vehicle's finish and provide additional corrosion resistance.



Replacing cab corners without welding provides a viable option for those who do not have access to welding equipment or prefer not to weld. By following the step-by-step procedure and taking necessary precautions, it is possible to replace cab corners and restore the structural integrity and appearance of a vehicle without welding.
