Installation Instructions
Before beginning installation, ensure you have all necessary tools and safety equipment, including safety glasses and gloves. Refer to the detailed instructions provided with your hitch for vehicle-specific steps and torque specifications.
General Installation Steps
- Inspect Vehicle Frame: Ensure the vehicle's frame is in suitable condition for installation, free from damage or excessive corrosion.
- Remove Obstructions: Temporarily remove any components that obstruct the installation area, such as exhaust hangers or bumper fascia, as indicated in your specific instruction sheet.
- Clean Weldnuts (if applicable): If your vehicle's frame has weld nuts that are corroded, clean them using a wire brush and penetrating lubricant. For extreme cases, a thread tap matching the hardware size may be necessary.
Video: This video demonstrates techniques for cleaning weld nuts on a vehicle frame, which may be necessary before installing a trailer hitch.
- Position the Hitch: Carefully raise the hitch into position against the vehicle's frame. Use jack stands or a second person to help hold the hitch in place. Ensure the hitch is level and all attachment points align.
- Fishwiring Hardware (if applicable): For attachment points within enclosed frame sections, use the provided fish wire to guide bolts and spacer plates into position.
Video: This video illustrates the fishwiring technique for installing hardware in enclosed frame sections, a common method for hitch installation.
- Drill Attachment Holes (if required): If your specific installation requires drilling new holes, use the hitch as a template to mark the locations. Drill a pilot hole, then gradually enlarge it to the required size using a cobalt drill bit with coolant.
Video: This video demonstrates the technique for drilling new attachment holes in the vehicle frame, if necessary for hitch installation.
- Secure the Hitch: Attach the hitch to the vehicle frame using the provided hardware. Hand-tighten all bolts initially.
- Torque All Fasteners: Once all bolts are in place and hand-tightened, use a torque wrench to tighten them to the exact torque specifications provided in your instruction sheet. It is crucial to follow these specifications to ensure a secure and safe installation.
- Reinstall Removed Parts: Reattach any exhaust components, bumper fascia, or other parts that were temporarily removed during installation.
Video: This video demonstrates the process of lowering and reattaching the exhaust system, which may be required during hitch installation.
