Final answer:
You should follow wheel lug nut and torquing procedures on U-Haul trailers whenever wheels are installed, as well as recheck torque specifications after the first 50 to 100 miles of towing to ensure safety.
Step-by-step explanation:
When towing a U-Haul trailer, wheel lug nut, and torquing procedures should be followed each time the trailer wheels are installed or follow any situation where they may have loosened. This is essential to ensure that the wheels are securely attached to the hub, preventing them from coming loose during transportation, which can lead to accidents or damage to the trailer. Torquing should be done in a star pattern to ensure an even distribution of pressure, and the manufacturer’s recommended torque specifications should be adhered to. After the initial installation, it is advised to recheck the torque after the first 50 to 100 miles, as lug nuts can settle and may require retightening.
