For many Acura RDX owners, the roof rails represent more than just an aesthetic enhancement—they are a functional addition that increases the vehicle’s utility. Whether for transporting bikes, gear, or luggage, roof rails provide a convenient and secure space to carry items. Fortunately, installing these rails is a task that many DIY enthusiasts can accomplish at home, avoiding the costs associated with professional installation. However, the process involves precision, the right tools, and a clear understanding of the vehicle’s design.
The following guide is based on user experiences, technical insights, and practical instructions shared across various online forums and product reviews. The focus is on the 2017 Acura RDX, but the general principles and steps also apply to similar models in the RDX lineup.
Overview of the Installation Process
The installation of roof rails on a 2017 Acura RDX is not a straightforward task—it involves cutting, removing, and replacing certain components of the vehicle’s roof lining. The process requires the use of a Dremel tool, socket wrench, and careful attention to detail. The rail system is designed to integrate with existing mounting points, and the installation involves removing factory-applied caulk, cutting into the roof cover, and securing the rails with nuts and clips.
One key challenge in this process is the need to modify the roof lining. Users have reported that the plastic molding covers must be carefully pried away and cut to accommodate the rail brackets. This requires patience and a steady hand, as improper cuts can damage the surrounding components.
The installation is further complicated by the need to ensure that the new roof rails align with the existing mounting brackets. Some users have encountered mismatched parts, particularly when using aftermarket components. In these cases, verifying the compatibility of the mounting brackets with the vehicle is essential before proceeding with the installation.
Materials and Tools Required
Before beginning the installation process, it is important to gather all the necessary materials and tools. The following items are typically required:
- Roof rails (either OEM or high-quality aftermarket alternatives)
- Dremel saw or similar cutting tool
- Socket wrench for tightening nuts
- Plastic trim tool for safely removing molding covers
- Screwdrivers (both flathead and Phillips)
- Marker or chalk for marking cut lines
- New roof rail covers (if provided)
Some users have also found it helpful to have a second set of hands, particularly during the cutting and alignment stages of the installation. The process involves working in tight spaces and making precise cuts, so having an assistant can help with holding tools or checking the fit of the rails.
Step-by-Step Installation Instructions
Step 1: Mark the Covers
Begin by placing the roof rails on top of the vehicle to determine where the cuts will be made. The rails are designed to bolt onto the car at specific points, and it is important to mark these locations accurately. Use a marker or chalk to indicate the areas that will be cut.
The roof rails are typically held in place by two studs on each side. The existing mounting points are already in place under the cover, so the cuts must be made to expose these points while ensuring the rail can be securely fastened.
Step 2: Remove and Cut the Covers
With the trunk or rear hatch open, gently start prying off the plastic molding covers that line the sides of the roof. These covers are held in place by a series of clips, and they must be popped off carefully to avoid damage.
Once the covers are partially removed, use a Dremel tool or other air saw to make the cuts along the marked areas. It is important to cut cleanly and precisely, as rough cuts can compromise the fit of the rails. Each side of the rail will typically require three cuts, as each part of the rail is supported by two studs.
After cutting, remove the caulk in the channel at the stud locations. It is recommended to remove at least two inches of caulk on either side of each stud to ensure a clean fit for the rail brackets.
Step 3: Install the Roof Rails
Once the cuts have been made and the caulk removed, place the roof rails into position. Secure the rails using the nuts provided, tightening them from the top. There are a series of nuts on each side of the rail, and they should be tightened in place to ensure the rails remain stable.
After the nuts are tightened, install the roof rail covers. These covers are typically designed to clip into place, so they should snap securely into position without the need for additional fasteners.
Step 4: Reinstall the Plastic Covers
Once the roof rails are installed, reinstall the plastic molding covers that were removed earlier. These covers are designed to snap back into place using clips, so they should be pushed into position carefully to avoid damaging the clips.
Before finalizing the installation, double-check that all components are securely fastened and that the rails are aligned properly with the vehicle’s structure.
Common Challenges and Tips
Mismatched Mounting Brackets
One of the most common issues users have encountered is the use of mismatched mounting brackets. Some aftermarket parts may not be compatible with the 2017 Acura RDX, particularly if the brackets are not designed for the specific model or year.
To avoid this issue, it is important to verify the compatibility of the mounting brackets before purchasing. If the brackets do not match the vehicle’s specifications, it may be necessary to contact the manufacturer or supplier for a replacement.
Difficulty Removing Plastic Covers
Another common challenge is the removal of the plastic molding covers that line the sides of the roof. These covers are held in place by clips and can be difficult to remove without damaging them.
Users have recommended using a plastic trim tool to gently pry the covers away from the vehicle. Starting from the rear and working forward is an effective method, as it allows the covers to be removed in sections without applying excessive force.
Precision in Cutting
The cutting process is a critical part of the installation and requires a steady hand and precise measurements. Improper cuts can lead to misalignment or damage to the surrounding components.
To ensure accuracy, users have emphasized the importance of measuring twice and cutting once. Taking the time to double-check the cut lines before making any cuts can help avoid mistakes and reduce the need for additional modifications.
Aftermarket vs. OEM Components
While many users have successfully installed roof rails using OEM (Original Equipment Manufacturer) parts, some have opted for high-quality aftermarket alternatives. These aftermarket options can be more affordable and still provide a similar level of fit and finish.
However, it is important to note that some dealerships may be hesitant to install or support aftermarket components, as they may not be covered under warranty. If professional installation is required, it may be more convenient to use OEM parts to avoid potential complications.
Users have reported that some aftermarket roof rails and running boards are designed to be nearly identical to OEM parts, offering a comparable fit and finish at a lower cost. When purchasing these alternatives, it is important to verify that the parts are compatible with the vehicle and that they include all necessary mounting hardware.
Cost Considerations
Professional installation of roof rails can be a significant expense. In some cases, users have reported that the cost of installation at a dealership can exceed $200 for roof rails and $100 for running boards. For those who are comfortable with DIY projects, installing the rails at home can save money while providing a sense of accomplishment.
However, it is important to consider the time and effort required for the installation. The process can be time-consuming, and users should be prepared to dedicate several hours to completing the task.
Final Thoughts on Compatibility and Safety
When installing roof rails on a 2017 Acura RDX, it is important to ensure that the components are compatible with the vehicle and that the installation is performed correctly. Improper installation can lead to safety issues, particularly if the rails are not securely fastened.
Users have emphasized the importance of following the manufacturer’s installation instructions carefully and ensuring that all components are properly secured. This includes verifying that the nuts are tightened to the correct torque and that the rail covers are in place to protect the mounting points from exposure to the elements.
