This can be a warped rotor or tire out of balance. If it only happens when braking it is a warped rotor.
High speed vibration is often an indication of a wheel that is out of balance or a bent rim. It can also be a bent driveshaft or bad U-joint. Vibration when you brake at high speed is almost always a warped rotor on the disk brakes.
If it varies with driving speed, look for an out-of-round tire. If it vibrates only when braking, you probably have a warped brake rotor.
no but it does reduce your control over speed and braking
Vibration of the car/steering which gets bad at a specific speed.
At low speed: Damaged or failed tire, bent wheel, damaged brake, damaged axle. Dangerous failure of a wheel bearing. At high speed generally a wheel balanace problem. While braking a bent or warped brake component.
Tire out of balance or bent wheel.
If the vehicle has hubcaps remove them and see if the noise stops. Check the brakes as well, something on the wheels is rubbing.
im guessing it has something to do with velocity and road conditions. yet again, if i'd imagine that a steering wheel shouldn't shake.... that can't be good.
Probably i would go for wheel balance and maybe check your wheel bearings rotors will not make it shake because of speed
It could be a shifted belt in one of the tires.
You will feel the steering wheel shake or judder in your hands at a certain speed. You will usually find it is ok at a lower speed then you feel the steering wheel shake as you accelerate and then disappears again as you go faster. Usually the shaking appears at exactly the speed you want to go (Murphy's law)
Could be motor mounts, the tires out of alignment or out of balance, or the steering needs work.
