A class-3 hitch is designed for heavy use and towing loads of 3,500 to 5,000 pounds. In this demonstration, we install a class-3 hitch on a 2000-model Ford Explorer. Materials: Trailer-hitch and installation hardware (included in kit)
Socket-wrench set
Torque wrench
Electric drill (Note: not necessary on all vehicles)
Safety glasses
For ease of installation and better viewing, our installation was done with the vehicle on a lift. The installation can also be done using an under-car jack and jack-stands. For added safety, chock the front wheels. - Safety tip: Wear safety glasses to protect your eyes anytime you are working underneath a vehicle.
This hitch comes in three main pieces: two side brackets and a center piece that includes the receiver. It attaches to the frame of the vehicle using the side mounting-brackets. Your installation kit should contain all of the mounting hardware that you'll need. Read and follow all instructions that come with your kit, since installation may differ somewhat depending on the style of hitch and your specific vehicle. - Attach the side mounting-bracket to the frame. If possible, use factory predrilled holes in the frame. (If there are no predrilled holes, or if they're not placed ideally for this installation, you'll need to measure and drill holes to accommodate the hitch.) The side bracket is secured to the frame at two attachment points. Use a single bolt and flange nut for the top attachment (figure A). For the lower attachment, use (from top to bottom) a bolt, bolt-plate, washer, lock-washer and nut. Repeat the process on the other side. Install all of the hardware but at this point, hand-tighten only. You'll want to make some final adjustments to the assembly before tightening everything down.
- Install the center piece between the two side brackets using knurled bolts, lock washers and nuts (figure B). The knurled bolts are designed to get a firm bite into the metal surface, so tighten them securely, but do not overtighten.
- With the assembly in place, use a torque wrench to tighten all the hardware to the specifications included with your instructions.
When you're ready to use your tow-hitch, insert the draw bar (the piece that the ball-mount is attached to) into the rectangular receiver in the center of the cross member. The draw bar is secured in the receiver using a metal pin and safety clip (figure C). The draw bar can be removed when not in use so that the hitch is less conspicuous. - Safety tip: When towing a large boat-trailer, lower the trailer onto the hitch and see that it seats properly on the ball-mount. Make certain that the pin and safety clip are in place and that the trailer lights are hooked up. Always use safety chains as an emergency backup in case of a hitch failure. For added stability, attach the chains in a criss-cross pattern.
