I have a 2000 Jeep Grand Cherokee Limited. I've been hearing a constant noise whenever I accelerate. The noise is hard to describe...it's not a grinding noise, but more of a light rubbing/whistling noise. It doesn't happen immediately upon acceleration, but whenever I get to around 10-15 mph the noise starts and continues, unless I'm coasting or slow way down. I mainly hear it on the drivers side. Any suggestions???

If you can get it to whistle at idle, use a peice of plastic tubing, say 1/4 in about 4-5 ft long. Long enough where you can hold one end to your ear (not IN your ear!) and move the other end around your engine compartment. Do some 'sniffing', where it sounds the loudest will be close to the area where your leak is. Replace any hoses that look 'iffy'. Hope this helps.

This is a symptom of the inlet manifold gasket having a leak.The whistling is air going in through the small leak/hole in the gasket.With the throttle butterfly shut,air is getting sucked in the only way it can.Try tightening the inlet manifold bolts 1st.But more than likely the gasket needs replacing.Hope this helps

sounds like couple things one you need check oil make sure it is not low on oil or over full and if it ok still doing it you may need a new oil pump it is faulty check oil level first when real low or high they do this too

What you are hearing is a vacuum leak. One of the vacuum hoses most likely came off. And is causing a whistling sound. Open the hood and have someone rev up the engine. Then by hearing the whistle you should be able to locate the leak. One of the vacuum lines could have broke, but usually you can cut it off and put it back on.
