Are you hearing knocking, rattling, or clunking sounds from your car as you turn the steering wheel? These are not normal noises to hear when steering an automobile.
At low speeds, the only noise you should notice when turning should be a mild hum coming from the power steering pump. If you hear any additional noises, you should pay attention to them.
The question is, why does a steering wheel create noise when turned? A whining noise may be heard while turning due to issues with the power steering system, such as low hydraulic fluid or a faulty pump. If your vehicle is making knocking or clunking sounds, it may have damaged bushings or ball joints.
In case you’ve been googling anything like “noise when turning steering wheel at low speed,” or “noise turning steering wheel” you’ve landed on the right page. Here are eleven of the most prevalent causes of noise when turning steering wheel at low speed.
11 Common Reasons For Steering Wheel Noise When Turning
1. Poor Fluid Quality
When attempting to spin the steering wheel of an idling vehicle, you may hear a severe grinding sound in addition to the usual whining. Incorrect lubricating fluid usage is indicated by these symptoms. Most modern automobiles are built to utilize only certain lubricants since their chemical compositions and the properties of the minerals are most suited for lubricating certain components.
The whole power steering system might be harmed if the improper lubricant is used.
2. Faulty Power Steering Pump
An automobile’s power steering pump may fail prematurely for a number of reasons, including unclean steering fluid, a worn steering belt, and others.
It will be more difficult to drive the car, and you may hear a whining sound when you spin the wheel.
If your car’s power steering pump breaks, it is a bad idea to drive your car and a potential hazard too.
3. Bad Power Steering Belt
The power steering pump and other engine parts get power from the engine through the serpentine belt (also known as the steering belt). Despite their durability, serpentine belts should be changed every 60,000 to 100,000 miles at the very least.
Slippage of a worn serpentine belt, brought on by the moving of the steering wheel, may cause an annoying whine or screech. If the belt fails completely, the alternator won’t be able to provide electricity to the engine’s various parts.
4. Low Tire Pressure
Problems with the suspension or power steering aren’t the only sources of noise at the wheel; low tire pressure may also generate a squealing sound as you turn.
Tires are constructed to resist the kinetic energy expended during a turn. However, the sidewalls of underinflated tires are more prone to bend and lose their form. Additionally, you may hear squeaking noises while turning the wheel, which is both annoying and risky.
5. Worn Out Shocks And Struts
Shocks, struts, or both are used in vehicles to help with handling and keep the tires in contact with the road. It is expected that these suspension components will serve you well for seven to eight years of daily driving.
When a car’s shocks or struts are worn, it might droop or lean to one side, making it unsafe to drive, especially at high speeds.
If your car’s shocks or struts are worn out, you may notice that it dives forward during braking or leans back under acceleration. Others have reported hearing a clunk or a whine as they spin the wheel.
6. Dried Out Ball Joints
Lubrication is essential for the efficient functioning of ball joints. On the other hand, age and the accumulation of dirt and road filth may cause this lubrication to become ineffective and cause failure.
Loose steering, uneven tread wear on the tires, and a clunking or rattling sound while turning the wheel are all symptoms of worn ball joints.
7. Faulty Power Steering Rack
A rack and pinion steering system relies on the steering rack as one of its primary components.
The steering rack is a durable component that is seldom in need of replacement. However, damage and early failure may be brought on by things like unclean steering fluid or a faulty steering pump.
A faulty steering rack often manifests itself in the form of a car that veers to the left or right at highway speeds. When spinning the wheel, particularly at low speeds, you may also hear clicking, clunking, or whining sounds.
8. Bad Suspension Bushings
Rubber or polyurethane suspension bushings serve to dampen vibrations and muffle outside noise.
Over time, the bushings in the steering wheel may dry up and break, causing a groaning or cracking sound while moving the wheel. There may also be clunking or rattling sounds, especially when braking hard or on uneven roads, and vibrations felt via the steering wheel.
9. Clogged Power Steering Fluid Reservoir
The hydraulic fluid is filtered to remove any harmful particles before it is pushed throughout the system. Every 30,000 to 50,000 miles is a good benchmark for changing the power steering fluid and filter.
Filter clogging reduces steering fluid flow if not addressed. The lack of power steering at low speeds might be caused by a blocked filter. Another symptom of a fluid leak is a whining sound when you spin the wheel.
10. Worn Tie Rod Ends
To enable the wheels to spin in response to the steering wheel’s rotation, tie rods, connect the rack’s ends to the knuckles at each hub.
Wear and tear on the tie rod ends might cause the steering wheel to shake or vibrate.
As the tie rod ends jiggle in their sockets, you could hear a banging noise whenever you move the wheel. Some motorists have reported hearing a clunking or creaking as they turn the wheel.
11. Power Steering Fluid Leak
Power steering fluid, a kind of hydraulic fluid, is necessary for the system to operate and lubricate the many moving elements.
When the reservoir tank is low or empty, it might indicate a leak in the power steering system, since power steering fluid seldom runs dry.
The most prevalent cause of system starvation is dry, leaking seals and gaskets. The steering wheel might generate a whining sound if the power steering pump is not lubricated.
Hearing Noise When Turning Steering Wheel at Low Speed? Here’s What To Do
Determine the source of the noise before attempting any repairs on your car. The vast majority of this can be done without the aid of a technician. Unless the problem is extremely complex, you may diagnose it and repair it on your own using basic mechanical tools, giving you the pleasure of a job well done. If your power steering issues are the result of installing non-original tires or driving on tires that are too worn, you probably won’t need to contact a professional.
Tires may be purchased and easily replaced at a local auto dealership utilizing a lug wrench, car jack, and wheel wedges.
You may use a dipstick to check and replenish your power steering fluid without the assistance of a mechanic. Most whining noises you hear when steering a parked automobile are caused by inadequate or low-quality steering fluid. Therefore, if you are having trouble steering or hearing strange noises coming from your car, you should first make sure there is sufficient lubrication in the steering fluid reservoir.
If you have a reliable under-the-hood work light, checking the power steering fluid may be done at any time of day or night. Pull the plug on the power steering reservoir and lower the deep stick within. You’ll need to take it out to compare the oil levels to the deep stick reading. If your power steering fluid levels are between the MIN and MAX indicators, your steering should be alright.
If your power steering fluid level is correct but you are still hearing noise, you may have used the incorrect fluid or the fluid may be contaminated. In either case, the power steering system must be flushed before being refilled with new fluid.
But if you sometimes find your power steering fluid level decreasing at an alarming pace, make it a practice to check for leaks around your power steering system’s hoses.
When trying to steer a parked automobile, loud clicking noises and intense screeching suggest a more serious technical issue with your power steering system. To determine which component needs repair or replacement, you may require an expert’s opinion. However, by lubricating the moving components of your automobile, you may significantly lower the level of noise being produced.
Is It Safe to Drive When the Steering Wheel Is Making Noise When Turning?
A strange noise while steering a vehicle is a sign of trouble. Drivers need to be careful. Even more so if you can’t figure out what made the noise you have heard.
While the significance of certain noise-making problems may be minimal in terms of danger or imminent component failure, others may presage such a threat with equal ease. Considering the risks involved, you should determine whether continuing to drive is worthwhile. Limit your time behind the wheel to a bare minimum.
The root source of any strange noise produced by the steering wheel should be identified as soon as possible.
Taking these precautions reduces the likelihood of subsequent problems and eliminates or greatly reduces the dangers of driving in this condition. Do not delay in contacting a reliable vehicle repair shop if you do not feel confident attempting these fixes on your own.
