the buttons and horn and stuff on the steering wheel slide on electrical contact strips behind the wheel... theres a coat of lube on this that can wash off with time and lots of Amor All down behind the steering wheel.. A little WD-40 sprayed into the switches and behind the wheel will probably fix this... Good luck.. also read the section on replacing the Horn Ring in a manual to get a picture in your head.. Everyone should have a manual for their vehicle, and the local library should have a professional shop manual available to make copies of for FREE...make the time to take time to read up on your vehicle, and work like the PRO'S! Good luck :) Dave Check the serpentine belt tension.
ummm power steering
ball joints or tie rods
A bad bearing can cause can the front end of car to make a squeaking noise when turning steering wheel either direction. It can also be caused by bad suspension.
could be struts and or strut brg plate that mounts the strut at the top
Most likely it is low power steering fluid. Check fluid and see if noise goes away.
The most common cause for a squeaking noise when turning the steering wheel on any vehicle, including a 2001 Toyota Avalon, is the belt that runs the power steering pump. If the belt is fairly new, a small drop of any dish soap on the belt while the car is running will clear up the noise. If the belt is worn, it needs to be replaced.
The problem is most likely a loose belt, this will happen when steering piston and pump is under a load as in turning. More torque is required to spin pulley.
Any bushing, if its worn or old enough, causes suspension squeaking at low speeds and when going over bumps. The typical cause of squeaking noises when turning the steering wheel is low power steering fluid. The power steering fluid reservoir should be checked and the fluid topped off if it is low. Fill your reservoir with manufacturer-specified fluid (or have your oil-change service station do it). With a very low fluid level, the whining sound will be accompanied by a difficulty in turning the wheel.
Many things can cause that, the simplest cause being lack of power steering fluid.
If the sound occurs only when turning, (left or right) the most likely cause is a loose power steering belt. First check to see if the belt is tensioned correctly, or in need of replacement.
Worn ball joints?
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.
A bad alternator. Turning the steering wheel all the way is very demanding on the power steering which draws power from the engine and can cause the idle to dip down. A weak alternator is usually the cause for the stalling.
Check out the bearings in the steering column and the knuckles in the steering shaft
I don't know exaclty, but I'm finding out the hard way! I have a 2001 Highlander and the steering wheel was 'squeaking.' I took it in and the shop lubed it for $25. This was summer of 2007. Since then the squeaking has come back and the steering wheel has gotten stiff. I just took my car in for new timing belt (scheduled maintenence) and found out that I'm now looking at $1,200 to fix the steering. If I could go back I would've gotten rid of it, but now I'm stuck with a big loan and a not so sound Highlander.
Anytime I've ever heard a humming noise when turning the steering wheel on any vehicle,It has always been due to low power steering fluid
Check and see if your power steering fluid level is low.
check the power steering rack or the steering pump
you have a bad power steering pump get a new one
This squeaking noise is just the body of the car under pressure. It is nothing to worry about.if you are still concerned take it to your local garage at get them to look at it.
Could be a worn belt, failing power steering pump or low power steering fluid.
Power steering belt.
It is most likely due to a loose power steering belt. If the steering wheel is hard to turn at speeds slower than 40mph or it gets harder the more you turn it and the squeaking noise happens when you turn the wheel, then you need to check the tension on the power steering belt.
If the steering wheel has radio controls on the wheel, there could be a problem in the wiring. When the wires connect electrically it will cause stations to change.
Well, if your steering wheel was crooked it can cause the car to lock up, jiggle the steering wheel WHILE turning the key in the ignition.
