The most common cause for steering wheel to squeak is either steering column or fluid. The Power Steering fluid cap is clearly marked and is located under the hood. Check either the "hot" or "cold" marker depending on whether your engine was recently running. Add the fluid, if it is low. If fluid is not a problem you may want to check the steering column's internal hardware. You can see if the internal hardware is properly tightened and lubricated. Using a silicone spray to help lubricate the knuckles (attachment point for the rod and wheel) may solve the problem.

The brakes can squeak, the suspension can squeak, the steering can squeak, the wheel hub/bearings can squeak, have a trusted mechanic determine the source of the squeak.
Loose alignment is the most likely culprit. It could also be the servo if your car has got one.
There is a small spring loaded metal contact which slides on a disk on the back of the steering wheel. Normally there is di-electric grease on the disk and over time it gets rubbed off and will start to squeak. Removing the steering wheel and adding some di-electric grease to the area should eliminate the sound.
Check your power steering fluid or your fan belt could be making noise.
Grease the rubber boot that goes around the steering shaft as it goes through the firewall.
Loose or worn out power steering belt. A power steering pump going bad.
Kinetic Energy helps the car wheel spin...
If it's comming from inside the steering wheel it's probably the horn contact. Otherwise it's probably a suspension part.
Low steering fluid can cause a steering wheel to whine when turning. A worn steering belt can also cause a steering wheel to whine when a car is being turned.
