Inspection, Service & Maintenance Hydraulic Reservoir LUG NUTS Lug nuts are prone to loosen right after a wheel is mounted to a hub. When driving on a remounted wheel, check to see if the lug nuts are tight after the first 10, 25 and 50 miles of driving, and before each tow thereafter. ! WARNING Lug nuts are prone to loosen after being first assembled. Death or serious injury can result. Check lug nuts for tightness on a new trailer, and after remounting a wheel at 10, 25 and 50 miles. 165 ! WARNING Metal creep between the wheel rim and lug nuts (bolts) can cause rim to loosen. Death or injury can occur if wheel comes off. Tighten lug nuts (bolts) before each tow. Tighten the lug nuts in three stages to the final torque for the axle size on your trailer, to prevent wheels from coming loose. Tighten each lug nut in the order shown in figure below. Use a calibrated torque wrench to tighten the fasteners. Verify that wheel studs are free of contaminates such as paint or grease, which may result in inaccurate torque readings. Over-tightening will result in breaking the studs or permanently deforming the mounting stud holes in the wheels, and will void the axle warranty.
