Question about 1998 Ford Explorer

1 Answer

I have a '98 Explorer w/5.0 motor. There's a "whining" noise under the hood. I'm pretty sure it's not the power steering pump because there's no power steering noise when I turn the wheel. What are the other choices?

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.

Whining noise when step on gas


Sounds like the power steering pump. check the fluid level. Have someone listen under the hood while you are turning the steering wheel. If the whine gets louder, your pump could be the issue.

Whining sound when turning


Please elaborate. Does it happen when stopped and turning the steering wheel, at certain speeds or both?
Does yours have power steering? That was an option for 1990.
First thing that comes to mind is the power steering pump or just low on fluid. Check the fluid level first. Not necessarily in danger of imminent failure but if yours has never been replaced it would be a good idea to get a new one for peace of mind.
One way to check it is to go to drive into a big empty parking lot, turn off the engine (don't turn the key too far as to lock the steering) and make some of the same kinds of turns that typically makes the noise happen. If it still makes the same noise it's NOT the power steering pump and I'm at a loss without more details. If it doesn't whine, then it still could be something with the power steering. With the car running and parked have someone turn the steering wheel back and forth and listen for it under the hood and you should be able to find the source. If you don't know where the power steering pump is I'd suggest getting a service manual. I recommend one from Haynes.

Whining noise when idlinng or under 2000 rpms


the most common cause of this on this model is the power steering pump, use a wooden dowel and listen to the pump with your ear against the dowel and the other against the pump body, I am sure u will find that the pump is noisy

Whininhg from power steering pump


That is the power steering belt routed around pump pulley that is slipping . The power steering is located behind the steering column, replacing and re-routing the belt is not an easy repair.

If instead the whining noise comes from under the hood , that is the serpentine belt, that is easier to repair.

98 gs300 loud screeching noise that last for about 5-10 seconds


The only four rotating items under the hood are
engine
power steering pump
A/C compressor
and smog emission pump.
==== I would check the fluid level on the power steering first. Check for pink fluid leak on the ground,
==== Check the A/C system with the wheel turn to one side and APPLY ALL LOADS.
Example: high beam on,A/C max,radio on and deforster on.
This will give you system a stress test.
All eyes on the pully and locate to part that generate the loud screeching noise.
My bet is on the power steering pump.

Please post more info on the comment window.
I will follow up on it.

Whining Noise


Sure sounds like a power steering pump, if they did not flush the grim out of the system from the old pump before they replaced the pump the new pump will fail in short order.
