How to Build a Sports Trailer
- 1). Unpack all the components after buying a sports trailer kit from a dealer. Lay out in an organized manner all the various pieces and hardware. Use a garage floor or an open workspace to do this. Look for and secure the assembly instructions.
- 2). Inventory all the parts to make sure you have everything you need according to the instructions. Prepare all the tools that will be necessary per the instructions to assemble the kit.
- 3). Locate the arm of the trailer which looks like a long rod or beam. Connect this part to the trailer frame, which looks like a large metal square frame. Bolt the beam and tongue parts to the frame using the provided hardware, crescent wrenches and a socket wrench. Attach it upside down and bolt it from the right side up.
- 4). Attach the trailer coupler -- the part that connects to the car hitch. Bolt the coupler to the trailer tongue to secure it to the trailer. Again use the socket wrench and crescent wrenches to secure the hardware.
- 5). Install the suspension and axle parts with the socket wrench, crescent wrenches and hardware consistent with the instructions provided in the kit. Install the suspension first so that the trailer axle connects to it when assembled -- it won't work the other way around. Tighten the hardware to secure all the parts together.
- 6). Turn the trailer right side up. Attach the wheel fenders and secure them with the socket wrench and crescent wrenches. Place the load bars that come with the kit on the top level of the trailer -- these support the equipment weight that will be added to the trailer. Bolt them to the frame.
- 7). Attach the wheels to the ends of the trailer axle on both sides. Slip the wheels on by inserting the axle into the middle of the wheel hub on either side. Hand-tighten the wheel nuts onto the axle inner hub so the wheel stays on. Tighten the wheel nuts with a socket wrench. Pump up the tires as needed with a tire air pump.
- 8). Attach and zip-tie the taillight wiring to the frame. Bolt the rear signals to the back of the frame using the socket wrench and crescent wrenches. Run the wiring to the front of the trailer and secure it with more zip-ties. Provide enough slack so the connector can dangle a bit from the front tongue of the trailer to plug it into your vehicle trailer socket as needed.
- 9). Obtain a trailer permit from your local department of motor vehicles. Attach the trailer license plate to the back of the trailer and keep it there at all times. Place the paperwork in the vehicle that will tow the trailer.
