The only thing that would cause this is a faulty power steering pump. Any shop can listen and confirm this.

What would cause whistling noise near pully and belt area noise gets louder with acceleration


The engine serpentine belt may be worn or wet. The belt slips, causing a high pitched squealing or whistle noise. The other possiblility is a bearing beginning to go out on one of your belt driven components

1999 Ford Ranger Front right brakes are making a grinding sound and a high pitch when i turn left, Do you know what it is ?


the grinding sound and the high pitch sound may not be related.
the grinding in the brakes means it is time to replace the brake pads / shoes and either replace or repair the discs and drums.

the high pitch noise that you are hearing while turning is more likely caused by a worn belt, low power steering fluid, or a faulty power steering pump.

Although it could be indicating something more serious like hub bearings going out, your best bet is to take it to a front end shop that offers free estimates and have them diagnose it in person.

hope this helps.

2004 ford freestar 4.2L engine...high pitched


this sounds odd but mine did this when i replaced the wipers. it seems the design of the wiper frame was making a whistle at higher speeds. the freestar wipers are exposed on the window cowl and not hidden so they endure the winds at high speed. it is worth a shot.

There is a humming sound coming from the front end of my 1999 oldmobile alero. Only happens when the car is moving. I dont hear itat idle or even when pushing the gas at idle. could it be my transmission...


Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!

High pitch whistling noise in engine compartment of 2005 envoy


There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.
