Before beginning the installation, the vehicle must be raised off the ground. This can be done using ramps or a suitable jack and jack stands. The manufacturer recommends placing the vehicle in "Very High" suspension mode to ease the installation process, especially when working on ramps. If using a hoist or lift, it is essential to utilize Tesla-approved lifting points and adapters to avoid damage to the vehicle’s structure.
Step-by-Step Installation Process
Step 1: Vehicle Preparation
Before starting the installation, ensure the vehicle is on a level surface and the battery is charged. Raise the rear of the vehicle using ramps or a jack, and if using a hoist, ensure that Tesla-approved lifting points are used. The vehicle should be in "Very High" suspension mode to provide easier access to the underbody components.
Step 2: Panel and Component Removal
Begin by removing the underbody panels and bumper fascia. This step involves the use of various tools, including screwdrivers, wrenches, and possibly a Dremel tool or jigsaw for cutting access holes. The installation guide provides detailed instructions for each component, including the specific tools required and the sequence for removal.
One of the key steps involves cutting an access hole in the bumper fascia to accommodate the ball-mount adapter. The template provided with the EcoHitch should be used to measure and mark the location for the hole. The center of the middle stud, as shown in the manual, should be used as a reference point. The recommended distance is 12.5 inches from the center of the middle stud toward the back of the vehicle. The crosshair on the template should be aligned with the left side of the oval hole to ensure proper alignment.
A 4” hole saw is recommended to begin the cutout, followed by an air saw, Dremel tool, or jigsaw to clean up the edges. It is important to note that the size of the hole may be adjusted based on the user’s preference, but the recommended size should allow for easy access to the ball-mount set bolt.
Step 3: Installation of the EcoHitch
Once the access hole is cut and the surrounding components have been removed, the EcoHitch can be installed. The installation involves securing the hitch using the provided hardware. The 1/2” x 13 x 2-1/2” bolt, 1/2” lock washer, and 1/2” flat washer are used to attach the ball-mount adapter to the hitch. The flat washer should be placed in contact with the hitch, and the bolt should be tightened until the lock washer crushes and the unit is secure.
After the ball-mount adapter is installed, the remaining components, such as the frame plate straps and Velcro squares, should be positioned and secured according to the manufacturer’s instructions. These components help to reinforce the hitch and ensure that it remains stable during use.
Step 4: Reassembly of Components
Once the EcoHitch is installed, the remaining components should be reassembled in the reverse order of removal, beginning with Step 14 of the installation guide. The bumper fascia and underbody panels should be reinstalled, ensuring that all hardware is properly torqued and secured. The manufacturer recommends following the installation guide in reverse to ensure that all components are reinstalled correctly.
Step 5: Final Inspection and Testing
After reassembly is complete, a final inspection should be conducted to ensure that all components are properly aligned and secured. The manufacturer also recommends testing the hitch to ensure that it is functioning correctly.
