Toledo Mechanic who does auto frame welding. At Expressway Mechanic on Duty we do auto frame welding and we weld suspension supports. Expressway Mechanic on Duty in Toledo specializes in shocks, struts, ball joints, tie rods, idler arms, sway bars, springs and all manner of a car’s suspension. The suspension is what makes a car travel smoothly down the road surface. Without a properly maintained and working suspension you would bounce down the road like an old wagon feeling every bump and losing control. There are various ways of attaching the wheels of the car so that they can move up and down on their springs and dampers, and do so with as little change as possible in the distance between adjacent wheels or in the near-vertical angle of the tires to the road. The front wheels must be free to pivot on their steering swivels. The driven wheels, whether front or rear, must also be free to rotate with the drive shafts.
