Rack and pinion steering is a crucial component of modern-day vehicles, and it plays a vital role in ensuring safe and efficient steering. 

The rack and pinion system is responsible for converting the rotational motion of the steering wheel into linear motion, which is necessary for turning the wheels. 

However, this system can develop issues that affect the vehicle’s steering performance over time; these symptoms are difficulty steering, uneven tire wear, excessive play in the steering wheel, fluid leaks, and strange noises.

This article will explore five bad rack and pinion symptoms you should know.

5 Bad Rack And Pinion Symptoms

Difficulty Steering

Difficult steering is one of the most apparent symptoms of a bad rack and pinion system. 

If you’re finding it hard to turn the wheel, especially at low speeds or while parking, this could be a sign of a problem. 

A faulty rack and pinion system will make it harder to turn the wheels, and you may feel resistance or binding while turning the wheel.

The first thing to look into is if the system has enough power steering fluid; if it does, the power steering pump in the rack and pinion system is on its last legs.

Uneven Tire Wear

Another sign of a bad rack and pinion system is uneven tire wear. 

If your tires are wearing unevenly or faster than usual, this could be due to a problem with the rack and pinion system. 

A rack and onion system has a lot of universal joints that wear down over time and cause play in the system that causes the wheels to oscillate and get uneven tire wear.

This oscillation can cause the car to shake at speed or when accelerating.

Excessive Play In The Steering Wheel

If you notice excessive play in the steering wheel, this could be due to a worn-out rack and pinion system. 

As mentioned above, with the uneven tire wear, the rack and pinion system has a lot of universal joints and the rack teeth and pinion gear that wear out over time and causes free play that you can feel through the vehicle’s wheel.

This is most prominent when trying to keep the car straight at speed, and you need a lot more steering input before the vehicle reacts.

Fluid Leaks

When the vehicle has hydraulic power steering, the rack and pinion system relies on hydraulic fluid.

If you notice any fluid leaks under your vehicle, this could be a sign of a problem.

The fluid will be red, but other power steering fluid colors are out there, so be wary of that.

Excessive power steering leaks can cause damage to the rack and pinion system, especially the power steering pump, as it uses oil as a lubricant.

The leaks can originate from the fittings for the low and high-pressure lines on the rack or the seals at the end of the rack where the inner tie rods attach.

Strange Noises

If you hear strange noises from your vehicle while turning the steering wheel, this could be due to a bad rack and pinion system. 

A faulty system can cause clunking or clicking noises while turning the wheel; this is due to the teeth on the steering rack or the pinion gear being so worn out that it skips or binds on a tooth.

Another noise that you might hear is clicking from the universal joints that rattle inside their housing, which is not normal and should be replaced.
