The steering gear, also known as the steering rack, is a crucial component of a vehicle’s steering system. It is responsible for converting the rotational motion of the steering wheel into the lateral movement needed to turn the wheels. When the steering gear starts to fail, it can compromise the vehicle’s handling and safety. In this article, we will discuss six common signs that steering gear is failing. Let’s explore them in detail.

A rack and pinion steering system is the type of steering system seen in many modern automobiles. The steering rack or gearbox is in the heart of the rack and pinion, which also includes universal joints, primary and intermediate shafts, and other parts. Through the steering wheel and steering column, the driver provides input to this central unit, which then transmits a mechanical signal to the tie rods and steering shafts to complete smooth and effective left and right turns. The steering rack or gearbox will eventually wear down, though. Repairing this crucial component quickly and effectively can make the difference between a small annoyance and a significant mechanical overhaul.
The beating heart of the steering system is the steering rack. The ability to drive your car is affected when it deteriorates or fails completely. This can be quite dangerous if it occurs while you are driving. Due to these and other factors, being aware of the warning indications of a damaged or malfunctioning steering rack or gearbox may help you avoid costly mistakes and save time and money.
Signs that steering gear is failing
Here are a few indicators or red flags that may indicate an issue with your steering rack is about to develop.
Difficulty turning the steering wheel
If you notice that it is difficult to turn the steering wheel, it could be a sign that the steering gear is failing. This can be caused by a variety of issues, such as a lack of lubrication or a problem with the power steering pump.
The power steering system that supports modern rack and pinion steering systems makes use of hydraulic pressure to enable simple and rapid steering wheel control. The steering rack or gearbox may get more heated or experience a loss of hydraulic pressure from the power steering unit when the steering wheel feels tight or is more difficult to turn than usual. In any case, it’s a persistent issue that needs to be checked out as soon as possible by an ASE-certified technician. This issue can occasionally be resolved and your steering rack’s lifespan increased by making a slight modification or adding additional power steering fluid.
Power steering, which is included in the majority of modern vehicles, maybe a sign that something is wrong with the system. To begin with, make sure the fluid reservoir is full. Fill it up if it isn’t. Check underneath the car for any indications of a fluid leak if, the next time you check, it has dropped once again. Leaks can occur in the steering rack itself, the steering pump, or the hoses.
Strange noisesloose steering
Grinding noise when turning the steering wheel. This is yet another indication of a steering gear problem.
If you hear strange noises coming from the steering wheel or the front of the vehicle when turning, it could be a sign of a problem with the steering gear.
A defective steering gear may cause a popping or grinding sound when the steering wheel is turned. Heat can accumulate in the steering gear component as a result of a leaky gasket or inadequate power steering fluid. The moving components of the steering gear are lubricated by the power steering fluid. Without the fluid, the friction causes heat to build up inside the steering gear component, causing the gear to wear out too quickly. A steering gear seal or gasket leaking fluid is indicated by puddles beneath the driver’s side of the car. Similar to how you check your oil level, periodically check the power steering fluid level.
Lack of adequate lubrication and maintenance is often the root cause of a faulty or malfunctioning gearbox. When you turn left or right, the extra heat promotes metal-on-metal contact, which produces a loud grinding sound. When turning and hitting a bump at the same moment, such as when entering a driveway, you can definitely hear this sound. If you hear this grinding noise when steering left or right, get in touch with a professional so they can immediately identify the issue and, if necessary, repair the steering gears.
Loose steering
If the steering feels loose or disconnected, it could be an issue with the steering gear. Component wear-out is the root cause of a loose steering wheel. The steering wheel will revolve so readily that it will seem as though it is not at all attached to anything. Instead of the entire steering wheel being loose, the symptoms of a loose steering wheel will feel slack in various spots. The entire steering will become loose if this is not addressed, making it hard to operate.
Additionally, if there is too much motion between the components of the steering gear, the steering of the car may seem sloppy and uncertain.
Burning oil smell
Another symptom might be brought on by a variety of other problems, but since it suggests a potential steering system failure, we must put it here. Fluid reaching or seeping into an overheated component is what causes the burning odour. If you notice even a slight whiff of pressure fluid in a power steering system burning, stop your car right once and call a repair. Pressure fluid in a power steering system smells very much like burning oil. Fires in an automobile can result from an overheated steering mechanism.
The smell of burning oil is a less frequent indicator of a broken steering rack or gearbox. The strong smell of burnt oil will be present when the steering gearbox is hot since power steering fluid itself has a strong odour of burnt oil. If this happens, stop your car right away, park it somewhere secure, and call a repair as soon as you can. When a steering gearbox overheats, continuing to drive might cause a fire and severe harm.
Any vehicle using a rack and pinion steering system must have a steering rack or gearbox to ensure smooth steering function. Contact a nearby ASE-certified technician as soon as you become aware of any of the aforementioned symptoms or warning signals so they can assess the situation and determine whether any damage has been done.
Leaking power steering fluid
As previously mentioned, tight steering can occasionally be a sign of low power steering fluid. The fluid levels won’t drop, though, because the steering box is hydraulically operated, unless there is a leak in the system. If you begin to leak power steering fluid, it is likely due to a loose fitting, damaged gasket, or other mechanical problem that has to be corrected right away. If this isn’t done, the steering rack or gearbox will get overheated, perhaps damaging gears and other crucial parts that might cause a collision.
When doing routine maintenance checks, another sign that the steering gear is defective arises. Power steering oil or fluid is foaming, stained, or has a milky appearance. Black fluid indicates that the steering gear has experienced severe heat build-up. The Oil that is foaming up indicates that the steering system is accumulating air and that the fluid is not lubricating the steering gear’s working elements. The presence of milky oil indicates that water has entered the steering system. The power fluid’s water content hinders the steering gear from receiving the required lubrication.
The scent of a leaking steering fluid may be used to identify it from other fluids (typically a burning oil smell). It will be leaking out the rear of your motor and will often be red or pink in colour. If you see this kind of fluid underneath your car, call a professional right away so they can check the leak and fix it before it causes more harm.
Any auto component that employs hydraulic fluid is susceptible to leaks, and the hydraulic steering assist is no exception. The operation of the power steering is impacted when one of the oil seals deteriorates and leaks. Keep an eye out for oil accumulating on the ground underneath the steering gear as a shortage of hydraulic fluid might harm the steering assist and the steering gear.
Vehicle Drifts or Pulls to the Side
Even when your car’s wheels are absolutely straight and its tyres have no symptoms of uneven wear, does it nevertheless pull or drift? You could have a damaged steering system. Too much motion between the gear’s components can induce drifting, and binding in the gear can make your car pull to one side even when you maintain the steering wheel stationary.
Can You Drive with a Bad Steering Gear?
Even if you can adjust for the many steering issues a defective steering gear may create, it is not a good idea to continue driving with it. The steering mechanism and the power steering pump may sustain long-term harm, particularly if the power steering also has a fluid leak. It is safer to swap out damaged steering gear as soon as possible.
