Understanding Track Rod Ends

Function of Track Rod Ends

Track rod ends are an essential part of a vehicle’s steering system, connecting the steering rack to the steering knuckle. They are responsible for transmitting the driver’s input to the wheels, allowing the vehicle to turn left or right.

The track rod end is a ball and socket joint, which allows for movement and flexibility while still maintaining a secure connection between the steering rack and the wheel. The ball joint is encased in a protective rubber boot, which keeps out dirt and debris and helps to prevent wear and tear.

Symptoms of a Failing Track Rod End

There are several symptoms that can indicate a failing track rod end. One of the most common is excessive play or looseness in the steering. This can make the vehicle feel unstable and difficult to control, particularly at higher speeds.

Another symptom is a knocking or clunking noise when turning the steering wheel. This can be caused by wear in the ball joint, which can lead to the joint separating and causing a loss of steering control.

A visual inspection of the track rod end can also reveal signs of wear and tear, such as cracks in the rubber boot or visible play in the joint. If any of these symptoms are present, it is important to have the track rod end replaced as soon as possible to ensure safe and reliable steering.

In conclusion, understanding the function of track rod ends and the symptoms of a failing track rod end is crucial for maintaining safe and reliable steering. Regular inspections and maintenance can help to prevent issues from arising and ensure the longevity of your vehicle’s steering system.

MOT Test Criteria

Steering System Inspection

During an MOT test, we thoroughly inspect the steering system of the vehicle to ensure that it is in good working condition. This includes checking the steering wheel, steering box, steering column, and all other components of the system.

We also check the power steering system, if the vehicle has one. We look for any leaks, damage, or wear and tear that could affect the performance of the system.

Track Rod End Condition Standards

One of the key components of the steering system that we inspect during an MOT test is the track rod end. This is the part that connects the steering rack to the steering knuckle, allowing the wheels to turn.

To pass the MOT test, the track rod end must meet certain condition standards. These standards include:

  • No excessive play in the joint
  • No damage or wear that could affect the performance of the joint
  • No excessive rust or corrosion that could weaken the joint

If the track rod end does not meet these condition standards, it will fail the MOT test. In this case, the track rod end must be replaced before the vehicle can be deemed roadworthy.

Overall, it is important to ensure that the steering system of your vehicle is in good working condition to pass the MOT test. Regular maintenance and inspections can help to identify any issues early on and prevent costly repairs in the future.
