A vehicle manual will indicate the proper torque rating and pattern for tightening lug nuts. Lug nuts should never be tightened in a circle, most use the diagonal method, but again check your manual. Vehicles are sensitive to the amount of torque the bolts apply and tightening should be done with a torque wrench. A plain impact wrench should never be used for the tightening of the lug nuts because most provide no control whatsoever over the amount of torque applied to the nuts. . There are also special torque-limiting extension sockets called “Torque Sticks” that can be safely used with an impact wrench to accurately tighten lug nuts. Another primary cause of warping is caused by excessive heat, which can soften the metal and allow it to be reshaped. Warping can also be caused by the disc being slightly overheated and th
