1999 isuzu rodeo

I have 1999 isuzu rodeo and makes whining sound. when is on park or moving the noise does not chage even when i turned the stering

i was thinking it was the power stering pump and i replace it but the noise still there

Please do not throw parts at it until you know what it is!
does it change with the speed of the motor.
A car care person should be able to use a stephascope and pinpoint where it is coming from.

What are you willing to do to determine what the noise is? You really don’t think anyone can give more than a guess based on the information you have supplied.

Would you be willing to remove your drive belts to isolate the noise?

The stethascope works good but it can still leave a measure of doubt.
