The installation of running boards on a 2017 Toyota Highlander requires careful attention to detail, particularly because of the vehicle’s underbody design and the specific mounting requirements of the TAC running boards. These running boards are engineered for a precise fit on 2014–2019 Toyota Highlander models and provide both functional and aesthetic benefits. This guide provides a detailed, step-by-step approach based on the technical specifications, product features, and installation instructions found in the source documentation.
Introduction
The TAC Running Boards (Model T132A-C800) are designed to improve accessibility and enhance the appearance of the 2017 Toyota Highlander. Constructed from aircraft-grade extruded aluminum and marine-grade stainless steel, these running boards offer durability, corrosion resistance, and a secure stepping surface. The product includes a 5.5-inch-wide corrugated rubber step pad with a polished stainless steel edge for an upgraded aesthetic. The installation process is designed to be straightforward, using pre-drilled mounting points on the vehicle’s underbody and all necessary hardware for a bolt-on installation.
Before beginning installation, it is important to confirm compatibility and prepare the necessary tools and materials. The following sections outline the tools required, pre-installation steps, and the installation procedure.
Tools and Materials
To install the TAC Running Boards on a 2017 Toyota Highlander, the following tools are recommended:
- Utility knife: Required for cutting around the mounting hole plugs.
- Leveler: Ensures the running boards are aligned and horizontal.
- Fine tip black marker: Used to mark bolt plates and directional arrows.
- Anti-corrosion sealant: Recommended for additional protection against rust and wear.
- Socket set: Includes 10 mm and 16 mm sockets, as well as a 2-inch extension for reaching tight spaces.
- Ratchet and wrench set: For tightening bolts and nuts.
- Deep sockets: Useful for working in narrow areas under the vehicle.
- Safety gear: Includes gloves, long-sleeved clothing, pants, and safety glasses.
The running board hardware is included with the product, so no additional parts need to be purchased. However, it is important to ensure that the vehicle is lifted to a safe working height and that the work area is clean and well-lit.
Pre-Installation Steps
Safety First
Before beginning the installation, it is important to wear appropriate safety gear. The installation process involves working under the vehicle, which can expose the user to sharp edges, dust, and potential hazards from the vehicle’s underbody. Wearing gloves, long-sleeved clothing, and safety glasses helps minimize the risk of injury.
Work Area Preparation
If working on a hard surface such as concrete, it is advisable to place a cardboard box or other soft material beneath the vehicle to provide a more comfortable surface. While a creeper is not typically recommended due to limited ground clearance on the 2017 Toyota Highlander, a low-profile work mat or padding can help reduce strain on the knees and back.
Marking Bolt Plates
To avoid confusion during installation, it is recommended to use a fine tip black marker to mark the directional arrows on the screw ends of the bolt plates. This step is particularly important for ensuring that the long ends of the bolts are oriented correctly during installation.
Accessing Mounting Holes
One of the key steps in the installation process is accessing the mounting holes on the underbody of the 2017 Toyota Highlander. These holes are typically covered by sealant and hidden mounting hole plugs. Using a utility knife, cut a circle around each plug to expose the mounting hole. There are 10 mounting holes in total.
After cutting, push the center of each mounting hole plug inward to lift its outer circumference, then carefully remove the plug. These plugs are not required for the final installation and can be discarded after removal.
Installation Procedure
Identifying Hardware
The hardware included with the TAC Running Boards consists of 10 mm and 6 mm hex bolts and nuts. It is important to note that 10 mm hex bolts and nuts require a 16 mm socket, while 6 mm hex bolts and nuts use a 10 mm socket. A deep socket and a 2-inch extension are recommended for tightening 10 mm bolts in tight spaces.
Installing Front and Rear Brackets
For a smoother installation, especially if working alone, it is advisable to start by installing the front and rear mounting brackets to the vehicle’s underbody. This step provides a stable base for the running boards and helps ensure proper alignment.
If working alone, it may be helpful to use a leveler to check the horizontal alignment of the brackets before securing them fully. This can help prevent misalignment later in the installation process.
Mounting the Running Boards
Once the front and rear brackets are in place, the running boards can be mounted to the vehicle. Begin by aligning the running board with the mounting brackets and inserting the bolts through the pre-drilled holes. Use deep sockets and a 2-inch extension to tighten the bolts in difficult-to-reach areas.
It is important to avoid fully tightening all bolts until the running board is properly positioned. This allows for minor adjustments to ensure that the board is level and aligned with the vehicle. Use a leveler to check for evenness and adjust as needed before final tightening.
Tightening and Final Checks
After the running boards are aligned, tighten all bolts securely using the appropriate socket and ratchet. A deep socket is especially useful for reaching tight spaces under the vehicle. It is important to ensure that all bolts are tightened to the manufacturer’s specifications to prevent loosening over time.
Once the running boards are installed, perform a visual inspection to ensure that they are secure, level, and aligned with the vehicle. Check that the corrugated rubber step pad is intact and that the stainless steel edge is polished and free of scratches.
Troubleshooting and Common Issues
Tight Spaces for Fasteners
One common challenge during installation is reaching and tightening nuts in narrow areas. To overcome this, use deep sockets and a 2-inch extension for your ratchet. If working in particularly tight spaces, consider taping the flat washer and lock washer to the inside of the bracket cavity before pushing the bracket over the bolt. This can help prevent the washers from falling out during installation.
Misaligned Running Boards
If the running boards appear uneven or not flush with the vehicle, do not fully tighten all bolts until the board is properly positioned. Use a leveler to ensure the board is horizontal and aligned with the vehicle. Adjust as needed before final tightening.
Compatibility Concerns
Some users may encounter conflicting information regarding compatibility with the 2017 Toyota Highlander. According to the documentation, the TAC Running Boards (Model T132A-C800) are confirmed to be compatible with the 2017 Toyota Highlander. Any discrepancies in older documentation or initial seller responses are incorrect, and the product packaging itself often confirms compatibility up to 2017 or 2019 models.
