The ARB bumper system for the Toyota FJ Cruiser is widely recognized for its robust construction and utility in off-road environments. However, as outlined in the installation experiences of several users, the process is not without its challenges. This article provides a detailed breakdown of the ARB bumper installation process, drawing from first-hand accounts and manufacturer instructions, with a focus on key considerations for U.S. consumers and DIY enthusiasts.
Installation Overview and Key Considerations
The installation of the ARB bumper system for the FJ Cruiser is a multi-step process that requires careful planning, appropriate tools, and a clear understanding of the hardware involved. The process includes the removal of the factory bumper, preparation of the mounting points, and the installation of the ARB bumper, often alongside additional components such as skid plates or a rear receiver hitch.
One of the central challenges highlighted in the source material is the ambiguity and lack of clarity in the provided installation instructions. Users reported that the instructions are often insufficient to guide a first-time installer through the more complex aspects of the process, particularly when it comes to identifying and organizing the hardware. The instructions also lack high-quality visuals or detailed illustrations to differentiate between bolt types and sizes, which can lead to confusion and delays.
Users also emphasized the importance of downloading and enlarging the installation instructions from ARB’s website, as the printed versions are difficult to read due to poor contrast and limited detail. This is particularly important for steps involving precise measurements and markings, which are critical to ensuring a correct fit and secure installation.
Tools and Hardware Requirements
A comprehensive list of tools is necessary for the installation of the ARB bumper system. The manufacturer recommends a basic tool kit, which typically includes:
- A 17mm socket or tube spanner
- Allen wrenches
- A power drill and various metric drill bits
- Snap-ring pliers
- A cold chisel
- A torque wrench (not explicitly listed in the instructions but essential for proper installation)
Additional tools that users found helpful but not listed in the official instructions include an air hacksaw for cutting the factory bumper, jigsaw, and hacksaw. While it is possible to proceed without some of these specialized tools, their use can significantly reduce installation time and effort.
One of the notable hardware challenges reported by users is the difficulty in identifying and organizing the various bolt sizes that come with the installation kit. The lack of clear labeling or visual differentiation between bolts of similar size (e.g., M6 x 20mm vs. M8 x 20mm) can lead to confusion and improper assembly. Users recommend sorting and labeling the bolts in advance to streamline the installation process and avoid errors.
Step-by-Step Installation Process
The installation of the ARB bumper system involves a series of interdependent steps, each of which requires attention to detail and precision. Below is an outline of the general installation process, based on the experiences of multiple users:
1. Preparation and Disassembly
The first step involves removing the factory bumper. This is typically a straightforward process, though users noted that the instructions provided by ARB could be improved. The removal of the factory bumper also requires cutting it to accommodate the ARB bumper, a detail that is not clearly communicated on the product page. This can be a surprising and frustrating aspect of the installation for those who are not prepared for it.
Once the factory bumper is removed, the next step involves preparing the mounting points. This may include cutting and shaping the existing bumper to fit the ARB components. As noted in the source material, it is highly recommended to use the downloadable installation instructions and enlarge the images for reference, as the printed instructions are difficult to read and interpret.
2. Test Fitting and Alignment
Before proceeding with the actual installation, it is important to test fit the ARB bumper to ensure proper alignment. Users reported that achieving an even fit can be challenging, particularly with the rear bumper. Uneven gaps on either side of the bumper were observed in some cases, and the cause was not immediately apparent. Adjustments may be necessary to correct these issues, and users were advised to torque the bolts to the specifications outlined in the instructions.
3. Hardware Installation
The installation of the ARB bumper requires the use of various hardware components, including bolts, nuts, and washers. One of the key challenges is ensuring that the correct hardware is used for each mounting point. Users emphasized the importance of organizing the hardware in advance to avoid confusion and errors during the installation process.
The instructions also mention the installation of cage nuts on the top of the bumper before attaching the cover trim and aluminum top. These components must be securely fastened to prevent vibration-related loosening. Users were advised to paint the aluminum top and button head cap screws black before installation to ensure a clean and uniform appearance.
4. Final Adjustments and Reassembly
After the bumper is securely mounted, additional components such as the exhaust mount and parking sensors must be reinstalled. This step is critical for restoring the vehicle’s functionality and ensuring that all systems operate correctly after the installation.
Users also noted that it is a good practice to recheck all bolt torques after a short period of use (e.g., one month of driving) to ensure that everything remains tight and secure. This is particularly important given the rough terrain that the ARB bumper is often used in, which can cause components to loosen over time.
Compatibility and Additional Considerations
One of the key considerations when installing the ARB bumper system is ensuring compatibility with the vehicle’s existing suspension and other modifications. For example, users who installed the OME 889 front coil springs reported that these were designed to work with bull bar bumpers that support winches. This highlights the importance of verifying that any suspension upgrades are compatible with the ARB bumper system before proceeding with the installation.
Another important consideration is the removal of the factory towing package. The ARB rear bumper is not compatible with the factory towing package, and it must be removed before proceeding with the installation. ARB offers an optional rear receiver hitch that can be used in place of the factory towing package, but this is a separate component that must be ordered and installed separately.
User Experiences and Feedback
Despite the challenges associated with the installation process, users reported a high level of satisfaction with the ARB bumper system once the installation was complete. The bumpers are described as solid and well-constructed, with no noticeable road noise or rattling. The powder coating also held up well under normal use, with only minor touch-ups required for chips caused by road debris.
Users also praised the built-in hi-lift jack points and the stability of the rear bumper, which provides a secure standing surface for accessing items on the roof rack. These features enhance the functionality of the ARB bumper system and make it a valuable addition for off-road enthusiasts.
However, users also expressed a desire for improved installation instructions that are more detailed and visually clear. This includes better illustrations of the hardware components, step-by-step visuals for the more complex aspects of the installation, and possibly even video tutorials for the more challenging steps.
Conclusion
The ARB bumper system for the Toyota FJ Cruiser is a robust and durable upgrade that enhances the vehicle’s off-road capabilities. While the installation process can be complex and time-consuming, users who have completed the installation report a high level of satisfaction with the final product. The key to a successful installation lies in careful preparation, the use of appropriate tools, and a clear understanding of the hardware and instructions provided by ARB.
Despite the challenges, the ARB bumper system is highly recommended for those seeking a reliable and functional upgrade for their FJ Cruiser. With proper planning and attention to detail, the installation can be completed successfully, providing a long-lasting and valuable enhancement to the vehicle.
