Purpose: Wheel balancing is the process of equalizing the weight distribution of a tire and wheel assembly to eliminate vibrations and ensure a smooth ride. Imbalanced wheels can cause uneven tire wear, steering vibrations, and handling issues. Procedure: A technician mounts the tire and wheel assembly on a balancing machine. The machine spins the wheel and measures any imbalance in weight distribution. The technician attaches counterweights to the rim of the wheel to offset the imbalance. The wheel is rechecked to ensure proper balance, and adjustments are made as needed until the wheel spins smoothly. Signs of Imbalance: Vibrations in the steering wheel or seat, especially at higher speeds. Uneven tire wear, such as cupping or scalloping. Steering wheel wobbling or shaking. Frequency: Wheel balancing should be performed whenever new tires are installed, after tire rotation, or if you experience symptoms of imbalance. Wheel Alignment: Purpose: Wheel alignment, also known as tire alignment, refers to adjusting the angles of the wheels to the manufacturer's specifications. Proper alignment ensures optimal tire contact with the road, improves vehicle handling, and prevents premature tire wear. Types of Alignment: Camber: The inward or outward tilt of the wheel when viewed from the front of the vehicle. Proper camber alignment ensures even tire wear and stability during cornering. Toe: The angle of the wheels relative to each other when viewed from above. Toe alignment ensures that the wheels are parallel to each other and perpendicular to the vehicle's centerline. Caster: The forward or backward tilt of the steering axis when viewed from the side. Caster alignment affects steering stability and returnability. Procedure: A technician uses alignment equipment to measure the current angles of the wheels. Based on the measurements and manufacturer specifications, the technician adjusts the camber, toe, and caster angles to ensure proper alignment. After adjustments are made, the technician rechecks the alignment to verify that it meets the required specifications. Signs of Misalignment: Uneven or rapid tire wear, such as wear on one side of the tread. Pulling to one side while driving, especially on straight roads. Steering wheel off-center when driving straight. Frequency: Wheel alignment should be checked annually or whenever you notice signs of misalignment, after suspension repairs or modifications, or when installing new tires.
