Car shakes at high speeds, steering difficult

I have a problem that is happening on a regular basis. While I'm driving at higher speeds around 75 mph, my car would start shuddering. I could feel it in the steering wheel, which then also becomes very hard to turn. What could be causing this?
Experienced mechanics share their insights in answering this question :
Hello. We will be happy to assist you. Your description makes me get the impression that the vehicle may have two separate issues going on. The vibration is likely to do with the motor mounts. The engine mounts loose the rubber reinforcement overtime and lose their ability to dampen vibration.

I believe your second concern with the vehicle being hard to steer would be related to a power steering pump or rack and pinion fault. I suggest that you have a technician inspect the condition of the motor mounts, your power steering system, and test the operation of your rack and pinion. Ensure that the rack and pinion is not having any loose parts comma which comely wear over time like tie rods and pinion seals.

How to Identify and Fix Common car Problems ?

Bad Bearings — Friction from bad bearings or inadequate lubrication can cause a shaky steering wheel. If bearings are the cause, you`ll notice that the shaking only occurs as you turn the wheel. To solve this problem, you can oil the bearings, or schedule a service appointment to replace them if there`s damage.
Poor bearings: Poor bearings are typically caused by damage or not enough lubrication. This causes friction and leads to the shaking of your steering wheel. You`ll most likely only feel this shaking when you`re turning. Simply clean your bearings before they need to be replaced!
Misalignment: The reason why your steering wheel is shaking may be the result of a misalignment. Similar to unbalanced wheels, when tires are moved out of their proper position from driving on uneven roads with potholes, railroads, and etc., the misalignment can cause steering wheels issues and more.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
Wheel Balance

When your car vibrates every time you drive at 50-70 mph, it is most likely that your wheels are out of balance. The vibrations will emanate from the steering wheel across the seat and through the vehicle`s floor.

The most likely cause of the shaking usually happens in the vicinity of your vehicle`s tires and wheels. They plant the car to the road, and if anything is out of alignment, you are going to feel it. It may be a broken control arm or a broken transmission mount.
Consistently shaking steering wheel when idling

Many don`t associate this as a symptom linked with power steering problems, primarily because the driver isn`t steering at that point. On-going, consistent shaking may be linked with other areas as well, such as a warped rotor or a problem with the engine mount.

The most common cause of a stiff steering wheel is the lack of enough power steering fluid in the system. This condition can arise if there`s fluid leakage from the pressurized hose area. Refilling the liquid in the power steering tank will fix the problem for the time being, but the leak must be taken care of.
Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly. Worst case scenario could be the rims themselves have become damaged or warped.
As you get into the higher speeds, if you distinctly feel vibrating coming from the engine, this could be a result of a lack of power, fuel, or oxygen getting to it. The spark plugs, fuel filter, and air filter should all be checked and replaced as needed.
The most common reasons for your car to excessively vibrate are a problem with your tyres, wheels, brakes, steering, suspension, axle or engine.
If the road is smooth and your ride still feels jerky, there`s nothing to blame except for the vehicle itself. Waiting for the problem to take care of itself will only make things worse, so we strongly suggest that you take action as soon as possible when you notice that your steering wheel is shaking.
The steering wheel of your vehicle will begin to shake if your tires are out of balance. You will begin to notice that it starts shaking at 50-55 mph. It may be okay at a lower or higher mph, but make sure to get those tires balanced as soon as possible for your tires` sake.

Waiting for the problem to take care of itself will only make things worse, so we strongly suggest that you take action as soon as possible when you notice that your steering wheel is shaking.
The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. This shaking starts at around 50-55 miles per hour (mph). It gets worse around 60 mph but starts to get better at high speeds.
Tires are out of balance, or possible a bent rim. Take it back to where the tires were put on and tell them you have a vibration. If you have a vibration when you are using the brakes that goes away when you take your foot off the brake you may have warped rotors.

Relevant Questions and Answers :

the most relevant questions and answers related to your specific issue

car shakes when idle and accelerating
ANSWER : It is very possible that you have a valve cover gasket or spark plug tube seal leak on your vehicle. These type of leaks will allow oil to leak onto the spark plugs causing misfires. When the engine misfires due to oil getting on the spark plug, the engine oil will burn. Since oil and tires are both petroleum products, they will both smell similar when they are burning. I would recommend having an oil leak inspection performed by a qualified professional to determine if there is an oil leak. Consider YourMechanic as an Oil/Fluid leak inspection can be peformed at your home or office.

Heavy shaking that stops at high speeds
ANSWER : Considering the mileage on your car, there could be some worn out pieces in the front and rear suspension. The links that attach the wheels to the body of the car have rubber pivot points that eventually lose their elasticity and begin to crack and tear. This might be what is causing your creaking sound. The vibration you’re getting may be related to that, or it could be that you have badly balanced or worn tires. Vibrations caused by an imbalance often go away above certain speeds. For your safety and peace of mind, you should have this checked out. You can have that done at your convenience by contacting Your Mechanic. They can send a technician to your home or office to check out your Hyundai and let you know what steps need to be taken.

If you was hooking up a OEM cooling fan that has only 2 wires and one speed but my car has a high and low speed, what wires would you hook up?
ANSWER : Hi there. Check the high and low circuits with a digital meter for a voltage reading. The low should have a lower voltage reading than the high. I recommend putting the wires on the high selection to prevent the engine from overheating at any time. If you need further assistance with hooking up your radiator fan motor, then seek out a professional, such as one from Your Mechanic, to help you.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

my car has theissue that it often lose power steering suddenly while turning.nothing leaks but there’s clunky noice when turning
ANSWER : The only way to determine if the collision caused damage is to carefully MEASURE the alignment and, as well, the frame dimensions using a tram. If those steps have not been specifically taken, what the mechanics have told you about "no damage" is meaningless. If the dealer has told you there is a problem with the steering rack, there very well could be and that possibility should be investigated. If the rack is faulty, it should be repaired or replaced. There is not supposed to be any clunking noises when you turn the steering wheel. The fact that there is a noise indicates a problem. The noise could be due to a problem with the strut bearing that allows the strut to turn freely with the steering knuckle, a defective tie rod end, a sway bar link or component and so forth. If you have hydraulically (not electric) assisted powered steering, loss of power assist could be due to a fault with the pump, the pump drive belt, or rack. Based on what you are describing, I would recommend you request a steering inspection – intermittent loss of assist and the responding certified mechanic will pinpoint the origin of the noise, as well as the cause of loss of assist, and get the required repairs implemented. With regard to the possibility of damage to the suspension and/or frame due to the collision, the ONLY way to determine that is to have those components measured using the appropriate tools and having in hand the Factory Service Manual which contains every relevant frame measurement for reference. You CANNOT visually look at a vehicle and determine if it is straight and undamaged because some of the specifications are measured within tens of thousandths of an inch (toe, for example) or tiny fractions of a degree (wheel camber). A carefully selected shop with trained individuals will have to perform such an inspection. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Reference point for the width of the car and correct steering method.
ANSWER : Hi there, thanks for writing in. Being that you’re a new driver, if you live in the United States; I’d take advantage of a great program aimed at teens called B.R.A.K.E.S. (Be Responsible and Keep Everybody Safe). It’s based in North Carolina, but they have BRAKES events across the US. They teach defensive driving tactics and also how to gauge the overall width, length of your vehicle.

Without knowing what type of vehicle you’re planning on driving first, it’s difficult for us to tell you what reference point is good. However, when driving, having your hands at 10 o’clock and two o’clock position is the best for easy and safe operation of the steering wheel. It’s also a good idea for you to take a basic driving education class; which can easily be researched online.

My car shakes and the wheel pulls to the right in a jerking motion
ANSWER : The pull, or jerking, at low speed could be due to an internal belt separation in the tread of a tire(s) which defect might not be externally visible. In a circumstance such as this, with the symptoms you are describing, IF the tires have irregular wear and less than 4/32 or 5/32 tread depth remaining, you should just replace the tires as a set, get them properly balanced and see if that resolves the issue. The alignment should also be verified immediately AFTER the new tires are installed (alignments with worn tires are not accurate). When replacing the tires, ask the shop to evaluate the wheels for damage and ask them to be sure each wheel runs true on the balance machine. If new, properly balanced tires do not resolve all the symptoms, I recommend you schedule a vehicle vibration diagnostic and a certified Mechanic will identify the issue during that and explain the needed repairs. Basically, with new balanced tires, if there is a remaining vibration it could be due to any rotating component and, as well, could be due to, or aggravated by, looseness or wear in the front suspension.
