More than likely, if the tire is not flat, and the steering wheel shakes, your problem is a bulge in your tire. As someone else has said, it is probably caused by a bad tire. It may have a broken belt. Also, some tires develop flat spots if the car sits too long. Does it happen constantly or just when you start driving? As a last suggestion, I would check that all of your lug nuts are on tight. If a wheel is loose, you might experience sloppy driving - especially going around corners. The problem should be resolved when the wheel falls off. The "bulge" refered to in answer 1, and the "bad tire" in answer 2 is PROBABLY the cause of your problem. However, a "broken belt" very seldom occurs, almost never unless the belt has been "cut" in a severe collision with a sharp edge. Also, answer 2 alludes to what we used to call, many years back, tire "morning sickness," which occured after a nylon belted tire had sat all night on the same part of the tire. The ground contact point of a tire is slightly flattened, and the nylon belts would take a temporary "set," so that until the tire was driven long enough to warm up the tread and nylon belts the temporary flat spot would cause a slight thumping and jarring. I thought that all nylon belted tires had been replaced by steel belted, meaning that issue should be non-existant today. As answer 2 asks and suggests, does it just do it [thump] when you start driving? If so, then it probably is morning sickness, and there is no cure, just live with until it is time to replace the tire(s). Also, you mention a slight shake in the steering wheel, which would suggest that the offending tire is one of your front tires. Even a thumping rear tire can be felt in the steering wheel, BUT you will also feel it more strongly through your seat if it''s on the rear. A thumping front tire can also be felt in your seat, but will feel, relatively, stronger in the steering wheel. The number one cause of bulging spots on radial tires is what is called "belt separation." A tire is made of several layers of belting material laid up like a sandwich, with the layers "glued" together. IF a flaw allows air from within the tire to work it's way into the sandwich, it can cause some of the layers to separate, fill with air, and cause a bulge, or "blister.' Due to the air pressure, this bulge can be very hard, and will cause the tire lift and thumping you describe. Answer 2 also makes a VERY GOOD SAFETY point, in that loose lug nuts on one of the wheels can cause a similar symptom, BUT left on it's own [withour proper retightening], will continue to become looser, until the wheel FALLS OF THE VEHICLE!!!! DO NOT allow this to happen. Periodicaly [spelling?] check the tightness of your lug nuts on all wheels, or have your tire service people do it. It could save your life!!!! Also, check and adjust your tire pressure REGULARLY, weekly at a minimum.
Usually when you hear a noise the tire is defective. Inspect the tire for a bubble.Good luck mike
I do not know when this questions was ask. In Ka steering noise .. show it immidiately to your dealer. I had similar problem with noise and hard seeting with funny noises. I end up with 2,000$ repair charges. Steering pump oli likage on battry charger and I need to replace all...
it sounds to be as if your power steering pump is out or low on fluid.
This could be caused by worn out ball joints, worn out constant velocity joints (if equipped), bad wheel bearing, worn out steering linkage, loose wheel nuts, cracked rim, worn out sway bar bushings or end links. Most of these are pretty serious, you need to have them checked ASAP. Losing a wheel at highway speed, which some of these can lead to, sucks, trust me I've seen it happen.
Warped rotors is the most likely cause. Seek professional help.
Have that tire checked sometimes the belts inside can break and cause a thumping noise
A busted motor mount, for one.
I think i can help; where are you from?
Many things can cause that, the simplest cause being lack of power steering fluid.
Maybe that thumping noise is the sound of another car smashing into the rear of your car.
A defective CV joint will make a grinding noise when you turn the steering will. A bad strut can also cause a grinding noise.
Take it to the garage and have them check for a cracked rotor or a loose caliper.
Bad tire? Rotate and see if thumping changes
More than likely the sway bar links - TSB on these
