What Do Tie Rods Do?

What are tie rod ends?

Irrespective of the type of steering system employed—whether it's rack and pinion steering or recirculating ball steering—they all rely on a crucial component for effective steering: tie rod ends. These components come into play every time you maneuver your steering wheel and are located on each front wheel, linking the steering gear to the steering knuckle. In essence, without tie rods, steering your vehicle would be impossible.

How do tie rods work?

Tie rods serve as the pivotal connection between the steering rack, steering arm, and steering wheel. They not only facilitate the movement of your wheels during steering but also enable turning.

Despite the differing mechanisms of the rack and pinion system and the recirculating ball system, both systems utilize tie rods to establish a connection between the steering rack and the steering arm, which, in turn, is linked to the steering wheel.

How are tie rods constructed?

Crafted from high-strength steel, a tie rod features a slender cylindrical design with two distinct sections. Comprising an inner tie rod and an outer tie rod end, they collaborate to deliver optimal wheel control. The inner tie rod incorporates an inline ball joint, linking it to the steering rack, while the outer tie rod connects to the steering knuckle.

What are the indications of a failing tie rod?

Given that tie rods are engaged every time you maneuver your vehicle, they are prone to wear and tear. Normal usage can gradually degrade a tie rod, but driving hazards such as rough road surfaces, potholes, and collisions can accelerate damage or lead to tie rod failure.

Should you encounter any of the following symptoms, it's crucial to schedule an appointment with your mechanic for a thorough assessment.

Signs of a bad tie rod include:

1. Uneven tire wear: Check both the inside and outside edges of your tires. Excessive wear on one side compared to the other may indicate tie rod issues.

2. Front end misalignment: Worn tie rods can lead to problems with front end alignment. However, other factors can also cause misalignment, so it's essential to consult your technician if you notice any issues.

3. Steering wheel vibration or looseness: Notice any unusual sensations in your steering wheel. A loose tie rod end can result in excessive play and cause shaking or vibrating.

4. Knocking sound during low-speed turns: If you hear knocking or unusual noises when making turns at low speeds, it could be a sign of worn tie rods. A professional inspection will confirm the diagnosis and ensure appropriate repairs are made.

How long do tie rods typically last?

Tie rods have the potential to endure for several years, and in some cases, they may never require replacement. However, the longevity of tie rods is heavily influenced by the driving conditions they encounter.

What are the consequences of tie rod failure?

The repercussions of tie rod failure can vary from mild, such as premature tire wear, to severe, including a complete loss of vehicle control. The condition of a failing tie rod can rapidly deteriorate over a short distance.

Is it safe to drive with a damaged tie rod?

Driving with a compromised tie rod significantly affects the steering and handling of your vehicle. You may experience wandering steering, resulting in reduced control over the vehicle's direction. If you suspect tie rod issues, it's crucial to promptly schedule an appointment with a technician for the necessary repairs.
