On a vehicle with rack and pinion steering, there is an inner tie rod end at each end of the steering rack. When the driver turns the steering wheel, the steering rack either pushes or pulls the front wheels. The steering rack transmits force to the tie rod end located near the wheel.
To replace the tie rod end, the wheel is removed and the outer tie rod end is removed from the steering knuckle. The tie rod end is then removed and replaced. Finally, the vehicle's wheel alignment is adjusted to the manufacturer's specification to ensure proper tire wear and steering characteristics.
