4. Setup and Installation
This section outlines the steps for installing your new rear bumper. Installation may vary slightly depending on your vehicle's specific condition and existing modifications.
- Prepare Vehicle: Park your Jeep TJ or LJ on a firm, level surface. Engage the parking brake. Safely lift the rear of the vehicle using a jack and support it securely with jack stands.
- Remove Existing Bumper: If an existing rear bumper is present, carefully remove all mounting bolts and detach it from the vehicle frame. Be prepared for potentially rusted or seized bolts, especially on older vehicles. Penetrating oil and appropriate tools may be necessary.
- Inspect Mounting Points: Clean any dirt, rust, or debris from the vehicle's frame mounting points. The Barnes 4WD bumper is designed to align with factory mounting locations. Some installations, particularly on older models, may benefit from drilling four additional holes (two on each side) on the inner mounting face plate for a more secure fit.
- Bumper Assembly (Optional): For easier installation, it may be beneficial to remove the inner mounting face plate from the vehicle, attach the new Barnes 4WD bumper to it using the provided hardware, and then re-install the entire assembly onto the vehicle frame. This can simplify access to difficult-to-reach bolts.
- Position New Bumper: Carefully lift and align the Barnes 4WD Rear Tail Plate Bumper with the vehicle's frame mounting points.
- Secure Bumper: Insert the provided mounting hardware through the bumper and frame holes. Hand-tighten all bolts first to ensure proper alignment. Once aligned, progressively tighten all bolts to the manufacturer's recommended torque specifications (if available) or standard automotive torque values for the bolt size.
- Consider Reinforcement: For optimal strength, especially when utilizing the recovery points for heavy-duty applications, consider installing additional frame reinforcement brackets (sold separately) that connect the bumper to the vehicle's frame.
- Final Check: Double-check all bolts for tightness. Ensure there is no interference with other vehicle components.
- Lower Vehicle: Carefully lower the vehicle from the jack stands.
5. Operating the Bumper
The Barnes 4WD Rear Tail Plate Bumper is designed for both protection and utility:
- Recovery Points: The integrated clevis mounts are designed to accept 3/4-inch D-rings (shackles) for vehicle recovery. Always ensure D-rings are properly rated for the intended load and securely fastened before any recovery operation. Use only appropriate recovery straps or ropes.
- Departure Angle: The bumper's compact design provides an improved departure angle, which is beneficial for off-road driving by reducing the likelihood of scraping the bumper on obstacles.
6. Maintenance
To ensure the longevity and performance of your Barnes 4WD Rear Tail Plate Bumper, follow these maintenance guidelines:
- Regular Inspection: Periodically inspect all mounting hardware for tightness. Re-tighten any loose bolts to prevent rattling or structural issues.
- Corrosion Protection: As the bumper ships in raw steel, it is highly recommended to apply a protective coating (e.g., paint, powder coat, or bed liner) immediately after installation to prevent rust and corrosion. Thoroughly clean and degrease the surface before applying any finish.
- Cleaning: Clean the bumper regularly to remove dirt, mud, road salt, and other corrosive elements. Use mild soap and water, then rinse thoroughly.
- Damage Check: After off-road excursions or impacts, inspect the bumper for any signs of damage, cracks, or deformation. Address any damage promptly to maintain structural integrity.
7. Troubleshooting
- Difficulty with Bolt Removal: If existing bolts are rusted or seized, apply a high-quality penetrating oil and allow it to soak for an extended period. Use appropriate tools such as a breaker bar or impact wrench. In extreme cases, bolts may need to be cut and replaced.
- Alignment Issues: If the bumper does not align perfectly with the frame, ensure all mounting points are clear of obstructions. Slight adjustments during the initial hand-tightening phase can help achieve proper fitment. Verify that the correct bumper model is being installed for your specific Jeep TJ or LJ.
- Rattling Noise: A rattling noise typically indicates loose mounting hardware. Re-check and tighten all bolts securing the bumper to the frame.
