YACT: What causes your steering wheel to vibrate at speed?

At about 70mph my car has a slight shake in the steering wheel. It's nothing too strong, but I wonder if it is a sign of something or just a normal occurence I hadn't really noticed before....
 
Tire balance or bent rim, alignment can't cause a vibration directly. It can wear the tires to the point that they vibrate, but the actual alignment won't make it shake.
Edit: Also a bad tire can cause this. e.g.: out of round tire, but not unbalanced.
 
well my tires were rotated just before I noticed this, so probably its a tire issue. The fronts were a LOT more worn than the rears, so clearly a rotation was in order...
 
My car does the exact same thing... it vibrates around 64-70mph range, it's the strangest thing. Going to get my tires balanced and alignment checked...

yea, any scalloping of the tires will cause this.
 
Tires, tire pressure, and wheel allignment.

Edit: I get vibration in my Miata at around 68mph. It's fine at 65 and 70 though.
 
It could also be your lower ball joints are shot. If you hit the brakes and get a lot of shake, I will almost gurantee that is the problem.
 
Either the tires or bad, the pressure in them is low or not the same in each tire, or they need to be balanced. If the car needs an alignment, the car itself will shake and you'll notice a pull in one direction.

Front wheel drive vehicle?s rear tires can get cupped from lack of rotation. After rotating the tires the cupping can cause slight to major vibration and noise.

Just my two cents, but it might be worth more to some else. 🙂

It's time for a new set of shocks/struts.

Hahahahahahahahaha.

No.

Worn out shocks/struts will not cause a vibration, they will cause the car to "float" because they are no longer damping the low-frequency oscillations of the coil springs. The entire car will be more "bouncy", but they will not cause a vibration in the steering.

Incorrect sir, worn shocks and struts can cause vibrations but generally at all speeds above 40 M.P.H., What occurs is the worn shock/strut allows the wheel tire combo to literally bounce rapidly causing a ocsillation which induces wheel shake.
This also causes the tire to wear in a cupping pattern across the entire tread which will worsen the condition, a out of spec toe (in or out) will cause cupping only on the inside or outside of the tread.

If your steering shakes only at one particular speed, it is most likely an out of balance tire or a out of balance rotor.


Looks like Zen beat me to it.

This coming from a guy who doesn't know what causes the steering wheel to vibrate at speed? Yea you're one to talk 😛 🙂

I just said that because it is the type of unecessary expensive repair that those guys would recommend...
 
Can warped rotors cause vibrations when brakes are NOT applied?

In my wife's car, a strong vibration started last week. I know the rotors are warped, but now it vibrates at any speed. You can even see the steering wheel shake. I'll be replacing the tires tomorrow, but I'm skeptical. Tires are worn, but unless they are desintegrating, I don't see how it would start vibrating all of a sudden.


Is there anything else that can cause vibrations, like bearings, or something with the steering itself?
 
GreenGhost, it's possible only if the rotors are severly warped. (enough warpage to cause the pads to oscillate in and out which in turn can cause the wheel to vibrate), it is uncommon though.

There are many things that can cause the steering wheel to vibrate including but not limited to the following ;

Out of baalnce tires
Worn ball joints
Worn tie rod ends
Worn steering rack or box
Worn drag link or relay arm
Worn struts
Worn shocks
Deteriated control arm bushings

All these cause your tires to wear unevenly which will cause steering wheel shake.
