Tie rods

Set up/Function

Tie rods act as the link between steering gear and steering knuckles and transmit the driver's steering movements to the front wheels. A tie rod consists of an inner and outer ball joint. The inner joint (steering gear side) transmits axial forces and is called the inner, or axial ball joint. The outer joint (wheel side) is called the outer, angular or radial ball joint. It transmits radial forces. The two ball joints are linked by means of an adjusting thread, which allows adjustment of the wheel track. Optimum track adjustment improves straight-line driving and reduces wear and tear on tires.
