What does a tie rod end do in car?

A tie rod end, also known as a ball joint, plays a crucial role in the steering system of a car. It is a mechanical component that connects the steering rack or steering linkage to the steering knuckles of the front wheels. Here are the primary functions of a tie rod end:

1. Allows for Smooth Steering: Tie rod ends enable the wheels to turn smoothly when the steering wheel is rotated.

2. Transmits Steering Input: When the steering wheel is turned, the tie rod ends transmit the steering movement to the wheels.

3. Maintains Wheel Alignment: Tie rod ends help maintain precise wheel alignment. This ensures that the tires roll straight and do not cause any deviations or pulling to one side.

4. Supports Weight: Along with facilitating steering, tie rod ends contribute to supporting the weight of the vehicle's front end.

5. Durability and Wear-Resistance: Well-designed tie rod ends are fabricated to withstand rigorous conditions, including high-impact forces and constant movement.

However, tie rod ends are relatively small yet vital parts within the complex mechanical system of a vehicle's steering setup. Regularly scheduled vehicle maintenance and any necessary replacements recommended by a qualified mechanic or through routine inspections are essential to ensure vehicle safety.
