Lemforder wheel alignment bolt
OE number 2197101

In a car, a wheel alignment bolt is a crucial component that helps adjust the alignment angles of the wheels. It is responsible for connecting the steering knuckle to the control arm. The bolt allows for precise adjustments to be made to the suspension and steering geometry, ensuring that the wheels are correctly aligned with each other and the vehicle's frame.

The wheel alignment bolt can be adjusted to control three key alignment angles: camber, caster, and toe. Camber refers to the vertical angle of the wheels, and an appropriate camber ensures equal tire contact with the road surface. Caster, on the other hand, relates to the forward or backward tilt of the steering axis. This angle affects steering stability and self-centering. Finally, toe indicates the angle at which the wheels point inward or outward when viewed from above. Adjusting these angles with the wheel alignment bolt helps optimize tire wear, steering response, and overall driving dynamics.
