The sound is probably from the power steering pump. If the sound gets louder when you turn the wheel, it's a sure bet. Check the fluid level, but with the age of the vehicle, the noise may be permanent unless the pump is replaced.

A worn front wheel bearing could cause a Grand Cherokee Limited to make a grinding noise when you accelerate. There could also be a problem with one of the shafts.

I have been told that this could be a bearing starting to go in the alternator. NOTE: I have not personally confirmed this yet, but I also have a high-pitched whining in my 93 Cherokee sport.

IT is your CV Joints which is making this noise.

If you're new to a supercharged car then you're most likely hearing the normal whine that a supercharger makes. They will whine louder the more you accelerate. 00gtp

the wheel bearing on the vehicle will make a roaring noise when you accelerate the faster you go the louder it gets

The cause could be your muffler. Mine has a hole in it and when I accelerate it roars, kind of like a vacuum.

yes, my 2000 grand prix gtp is losing power and makes ticking noise.

A whistling noise indicates a vacuum leak.

I have a 1994 Grand Marquis and the buzzing noise that I hear every once in awhile is the load levelers (rear shock system) filling with air. Maybe this is what you are hearing and it is a coinencedence that it stops when you accelerate My 1994 Grand Marquis does something like that...it's the air intake thing (press the gas pedal, it moves a valve at the end of the overhead cam). That valve can stick open slightly and hum. You may notice the car idles faster when it buzzes. This can be fixed by going over the edge of the valve with fine sand paper.

It is quiet obvious when you have a turbo because when you accelerate you hear a whistling sound. The turbo noise is unmistakable.

Your power steering has a problem. It could be a broken part, or you may need a whole new set-up.

I would say you either have a rod knocking or lifter knocking. I know in the 3.8 litre motors they are known to knock alittle when you cold start them. Most Grand Ams, Grand Prixs are like this. My sister has a 2002 Grand Am that does this and the noise goes away once it's warmed up. I would also double check and make sure your oil is full. get your car to a garage for a def solution.
