Purpose: Wheel balancing ensures that the weight distribution around the wheel and tire assembly is uniform, preventing vibrations and uneven tire wear. Procedure: Mount the wheel and tire assembly on a balancing machine. Spin the wheel to determine any imbalances. Attach counterweights to the wheel rim at specific points to offset imbalances. Recheck the wheel to ensure proper balance. Repeat the process if necessary until the wheel is balanced within acceptable tolerances. Signs of Imbalance: Vibrations in the steering wheel or vehicle floor at certain speeds. Uneven tire wear, such as cupping or scalloping. Steering wheel wobbling or shaking. Benefits: Smoother ride and improved vehicle handling. Reduced tire wear and prolongation of tire life. Prevention of premature wear on suspension components. Wheel Alignment: Purpose: Wheel alignment ensures that the wheels are properly positioned relative to each other and to the vehicle's frame, optimizing handling, tire wear, and fuel efficiency. Types of Alignment: Front-end Alignment: Adjusts the front wheels' camber, caster, and toe angles. Four-wheel Alignment: Includes adjustments for all four wheels, ensuring proper alignment of the rear wheels as well. Adjustable Angles: Camber: Vertical tilt of the wheel; excessive positive or negative camber can cause uneven tire wear. Caster: Forward or backward tilt of the steering axis; affects steering stability and returnability. Toe: Angle of the wheels relative to the vehicle's centerline; improper toe alignment can lead to tire scrubbing and uneven wear. Procedure: Use alignment equipment to measure current wheel angles. Adjust camber, caster, and toe angles as needed to align with manufacturer specifications. Test drive the vehicle to confirm proper alignment and handling. Provide alignment specifications report to the customer. Signs of Misalignment: Vehicle pulling to one side while driving. Uneven tire wear, such as wear on the inside or outside edges. Steering wheel off-center when driving straight. Steering wheel vibration or instability. Benefits: Improved steering response and handling. Reduced tire wear and prolongation of tire life. Enhanced fuel efficiency by reducing rolling resistance.
