WHAT IS A TIE ROD END? A tie rod end is an important component of the car's control system, commonly found in most four-wheeled vehicles. Each front wheel of a car requires an inner tie rod end and an outer tie rod end to connect the steering knuckle and rack end.WHAT IS DIFFERENT BETWEEN INNER AND OUTER TIE ROD END? The inner and outer tie rod ends differ in terms of their location and function. The inner tie rod end serves as a connection point between the outer tie rod and the steering gear. Its primary function is to enable smooth and controlled movements of the wheels. It plays a significant role in wheel alignment, contributing to a comfortable and stable ride. On the other hand, the outer tie rod end is a flexible component that can be adjusted to establish the alignment angle of a vehicle.WHY ARE TIE ROD END IMPORTANT? Tie rod ends are crucial components of a vehicle's steering system that connect the steering rack or center link to the steering knuckle. Typically located at the outer ends of the steering rack or center link, tie rod ends are attached to the steering knuckle using ball and socket joints. We essentially serve as the pivot point between the steering system and the wheels, facilitating the transmission of steering input from the driver to the wheels. In simple terms, without tie rods, you cannot control a car.SYMPTOMS OF A BAD TIE ROD The inner tie rod is an essential component of a vehicle's steering system as it connects the steering rack to the tie rod end. A damaged tie rod can cause various symptoms that affect the vehicle's steering and handling. Here are some common signs of issues with the inner tie rod:Uneven Tire Wear: One of the most noticeable symptoms of a bad tie rod is irregular tire wear. The vehicle's tie rods directly influence the front-end alignment, resulting in unexplainable feathered inboard/outboard tread wear patterns.Unresponsive Steering: A significant sign of tie rod wear is a general lack of steering responsiveness. This occurs due to increased free-play between the articulating outer end of the tie rod and the steering knuckle.Abnormal Noises When Steering: In severe cases, worn tie rod ends can produce popping or clunking noises when turning the steering wheel. These noises are caused by heavy wear within the ball and socket of the tie rod's outer end.Vibration or looseness in steering wheel: Tie rod wear may also lead to vibrations felt through the steering wheel, especially when driving over uneven terrain or negotiating turns at lower speeds.HOW TO CHOOSE HIGH-QUALITY TIE ROD END? Tie rod ends are absolutely essential parts in a car's steering system, and choosing a high-quality and durable tie rod end is a critical consideration.
