2. Lower the Exhaust System (Temporarily)
- Locate Exhaust Hangers: Identify the rubber exhaust hangers that support the exhaust system. Typically, there are two or three located near the rear of the vehicle.
- Apply Penetrating Oil: Spray penetrating oil onto the exhaust hangers to lubricate them. Let it soak for a few minutes.
- Remove the Hangers: Using the exhaust hanger removal tool or a flathead screwdriver and pliers, carefully detach the exhaust hangers. Be cautious not to damage the rubber hangers. Pro Tip: Soapy water can also act as a lubricant.
- Support the Exhaust: Once the hangers are removed, the exhaust system will hang lower. Support it with a strap or bungee cord to prevent it from straining any connections.
3. Prepare the Mounting Points
- Locate Mounting Holes: Identify the pre-drilled mounting holes in the RAV4’s frame. They are typically located on the underside of the frame rails, near the rear bumper.
- Clean the Mounting Holes: Use a wire brush to clean any dirt, rust, or debris from the mounting holes. This ensures a clean and secure connection. Spray with penetrating oil.
4. Install the Trailer Hitch
- Position the Hitch: With the help of your assistant, carefully lift the trailer hitch into position, aligning the mounting holes on the hitch with the corresponding holes in the RAV4’s frame.
- Install the Hardware: Insert the provided bolts and washers through the hitch and into the frame. Start with the bolts hand-tight to ensure proper alignment.
- Torque the Bolts: Using a torque wrench, tighten the bolts to the manufacturer’s specified torque specifications. This is a critical step for ensuring the hitch is securely attached and safe for towing. Consult the hitch’s installation instructions for the correct torque values. Tighten in a star pattern to evenly distribute pressure.
- Double-Check: Carefully inspect all bolts to ensure they are properly torqued.
5. Reinstall the Exhaust System
- Reattach Exhaust Hangers: Carefully lift the exhaust system back into position and reattach the rubber exhaust hangers. Ensure they are securely fastened.
- Remove Support Strap: Remove the support strap or bungee cord that was holding the exhaust system.
6. Final Checks
- Inspect the Installation: Visually inspect the entire installation to ensure all bolts are tightened, the exhaust system is properly supported, and there are no loose connections.
- Lower the Vehicle: Carefully lower the vehicle back to the ground.
- Reconnect Battery (If Disconnected): If you disconnected the battery, reconnect the negative terminal.
Congratulations! You have successfully installed a trailer hitch on your 2017 Toyota RAV4. Before towing anything, it’s always best to double-check your work and familiarize yourself with the hitch’s weight capacity and towing guidelines.
Frequently Asked Questions (FAQs)
FAQ 1: What class of trailer hitch is best for my 2017 RAV4?
Generally, a Class III trailer hitch is the most suitable for a 2017 Toyota RAV4. Class III hitches typically have a 2-inch receiver and can handle a gross trailer weight (GTW) of up to 5,000 pounds and a tongue weight (TW) of up to 500 pounds, although you must always check your RAV4’s owner’s manual for its specific towing capacity, which may be lower. Avoid Class IV hitches, as they are usually overkill for a RAV4 and may require modifications.
FAQ 2: What is the towing capacity of a 2017 Toyota RAV4?
The towing capacity of a 2017 Toyota RAV4 varies depending on the model and configuration. Typically, it ranges from 1,500 to 3,500 pounds. Consult your owner’s manual or the sticker on the driver’s side doorjamb for the exact towing capacity of your specific RAV4. Exceeding this limit is dangerous and can damage your vehicle.
FAQ 3: Do I need to install a wiring harness for trailer lights?
Yes, if you plan to tow a trailer with lights (brake lights, turn signals, running lights), you will need to install a trailer wiring harness. This harness connects to your RAV4’s electrical system and provides the necessary signals to the trailer lights. Several plug-and-play wiring harnesses are available specifically for the 2017 RAV4.
