Question about 2001 Hyundai Tiburon

1 Answer

Power Steering Noise

My son's car used to make the whining noise usually associated with power steering only when he turned the wheel to the left and right limits. I replaced the pump and now noise happens intermittently when I start the car and turn the wheel. If I drive the car, the noise occurs at turn limits or not at all. I bled the system per the service manual - jacking up the front end and turning the wheel back and forth several times.

Also, there is some confusion as to what fluid to use. The book says PSF-3 but the auto parts store had never heard of it. I've also heard of using Dexron ATF. I added some regular steering fluid (not ATF). The level didn't drop much after I changed the pump.

There are no leaks from the rack (yet). Am I using the right fluid? Is the viscosity of power steering fluid different from ATF? What's causing the recurring noise?

    I have the same issue with a 98 Tiburon. I do know that in 98 you use ATF Dextron III. This info came from the after market chiltons repair manual. I too don't have any leaks and am worndering if it is my Rack and Pinnion. I'll stay posted with updates.

Use what the manual suggest to use. it should be standard power steering fluid. do not use ATF. ATF is automatic transission fluid.
you only use this if the manual says to usually only on a merzades.
the wining noise could be the pump breaking it's self in. it will do this for a while untilt he pump is completley broke in and is used to the being used.

I have a 2001 chevy astro ls awd van. It has a constant whine, in park, driving, acceleration, and deceleration. Any suggestions?

failing alternators are famous for noise. Does it change pitch when you turn on a bunch of accessories, or turn the steering wheel? Could also be either water pump or power steering. The are the three most common culprits. Check your fluid level in the power steering. Usually if power steering the noise will change when you turn the wheel. Listening under the hood may help you to determine area noise is coming from more clearly.

While driving steering wheel locked up

Sounds like your power steering fluid is low. Steering suddenly becomes very hard, then frees up. Did you perhaps hear a whining noise at the time?. Under the hood, find the power steering pump and / or top up bottle, and check the level. Usually a small dip stick is built into the screw top and marked. Use only correct fluid type.

2002 kia optima,,, whining noise that stops when turning left

power steering pump probably went out.. if you can easily get at the belt and are any kind of mechanically inclined, remove the drive belt to the p/s pump and then start the car if the noise is gone then its probably part of the power steering pump

Whining when i press gas

normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.

oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Whining noise from steering when turning steering wheel left or right even when parked with engine running

Check the level in the power steering fluid reservoir. You most likely need a top up. The noise is caused by the pump effectively pumping air through the system. Top up to the level marked in the reservoir then turn on the engine and move the steering wheel around for a wile then turn off an re top up to the level marked in the reservoir and all should then be OK. Make sure you use the correct fluid for the car – usually a Red Dexron Hydraulic Fluid.

Making noise when turning steering wheel but no leakage

The power steering pump that is used in your car is notorious for noise issues, it is a loud whine which gets louder as you turn the steering wheel right or left, flush the system fluid and replace the pump.
