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.

Its most likely in need of CV axle replacements up front. My 1995 Grand Cherokee experienced the same problem. I had it priced for replacement at a local garage and they wanted $389.67 for replacement.

I found them on eBay for $98.00 plus $20.00 shipping.

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.

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.
