I have a Jeep Grand Cherokee and began hearing a high pitched whistling sound coming from the front end during acceleration. It typically stops when I let off the gas but starts again when I accelerate. The dealership had it for 6 days and can't find the problem. When I hear the noise I can feel a slight vibration under my feet as I drive. Any suggestions?

 

Most likely front diff, but there are also bearings to check,get under there,open the diff cover,had the same problem

 

What year is your Jeep?

 

It's a 2007.

 

If you have less than 36000 miles on it, you may have warranty coverage. You might want to look into that.
