Wheel Balancing: Purpose: Wheel balancing is the process of evenly distributing the weight of a tire and wheel assembly to ensure smooth rotation and minimize vibrations while driving. Procedure: A technician uses a wheel balancing machine to measure any imbalances in the tire and wheel assembly. Small counterweights are then attached to the rim to offset any heavy spots and achieve a balanced rotation. Importance: Proper wheel balancing reduces tire wear, improves vehicle stability, enhances ride comfort, and minimizes stress on the suspension components. It also prevents vibrations that can lead to steering wheel shimmy or uneven tire wear. Wheel Alignment: Purpose: Wheel alignment, also known as tire alignment, refers to the adjustment of the angles of the wheels relative to each other and the vehicle's frame to ensure optimal tire contact with the road surface. Types of Alignment: There are three main types of wheel alignment: Toe Alignment: Adjusting the angle of the wheels inward or outward when viewed from above. Camber Alignment: Adjusting the angle of the wheels inward or outward when viewed from the front of the vehicle. Caster Alignment: Adjusting the angle of the steering axis when viewed from the side of the vehicle. Procedure: A technician uses alignment equipment to measure the current alignment angles of the wheels and makes adjustments as necessary to bring them within the manufacturer's specifications. Importance: Proper wheel alignment ensures even tire wear, improves vehicle handling and stability, enhances fuel efficiency, and reduces strain on the suspension and steering components. It also helps maintain straight-line tracking and prevents drifting or pulling to one side while driving.
