Is your Liberty making strange sounds? Can't figure out the source of some mysterious noise? Are you being distracted by some irritating noise? We'll discuss it here!
 
Also, related discussions are being consolidated here so don't be concerned if some messages appear to be out of order!

2005 Renegade windshield noise by whersmyspex

Hello,
 
Our 2005 Liberty Renegade has the usual windsield problems, we are on our third windshield now. About two months after the last replacement, we began hearing a relatively high-pitched whistle coming from the right side of the windshield or passenger door area. It is very hard to localize and sounds a lot like a one-note harmonica. It only happens above about 65 mph and is worse on hot days than cool ones.
 
We've had the autoglass replacement techs look at it three times. The windshield is installed correctly and is sealed. No water leaks in. They even added a bead of that expanding foam insulation inside of the passenger side seal around the top of the door, to no avail.
 
Has anyone else experienced anything like this? It's driving us nuts...

I know two methods to locate thin cracks:
  
- apply masking tape over the windshield joint and you progressively remove it until the noise comes back. Once an area is defined pour alcohol (from outside) along the joint. This should momentarily fill the crack and help locate the problem by stopping the whistle. Wax is later applied around that region. Alcohol also cleaned the surfaces.
 
- a high frequency microphone (ultrasonic) that you drag around the periphery of the windshield from inside when the truck moves at 65 mph. A meter or diode indicator will reveal the high pitch sound source when passing above the crack.

Great tips! It sounds like a good candidate for a Guide - see the link at the top of this page.

or passenger door area.
 
When driving so as to adequately produce the noise have a passenger push outward on the passenger side door/glass usually at the upper front corner. The pitch or sound level will change dramatically if it is the door seal. On small cheesy vehicles it does not take much pressure to reveal the location of such an air leak that will not usually leak water. I may take a pretty good push on a Liberty to reveal this kind of leak.

I have a '02 Liberty Limited 2WD with almost 60k miles. I drove about 300 miles yesterday, and when I turned off the engine last night, I heard a bubble/gurgling noise coming from under the hood.
The noise lasted less than 5 minutes, and I noticed a little steam coming out from under the hood. This morning I checked and found no leaks anywhere and the coolant level was fine.
Any ideas what it was?

If you see steam and have not driven through a pond, you're loosing liquid
Check your hose connections and rinse the gasket of your cooling circuit filler cap under running water. The aging antifreeze could make it stick and build overpressure. My hoses are still like new at an equivalent mileage.
