Jeep Liberty Noises and Sounds

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! :)

  • '02 Liberty with 90K running 5W-30 fully synthetic. Starter catches fine and starts right up, but any outside temp below about 40F and it sounds like a jet engine winding up or a wild cat with its tail in a fan under the hood. Only does this on cold starts and it goes away after about a block. No engine light, loss of power or anything else that would give me an obvious reason. I just don't want to find one morning this has caused some major damage somewhere. Any ideas??

    Luraye... It could be the fan clutch or the water pump.

  • I am having the same issue. Did you have it looked at? What did they determine?
  • I was told to have the serpentine (drive) belt changed. So, $100.00 later, the noise is less, but still present. A mechanic friend says that it is because it has just been so bleepin' cold (staying around zero). I've checked the fluid levels and since it quits once it warms up, I'm not going to worry about it until I can feel my toes again!! Let me know if you have any better luck!! :shades:
  • I've checked the other posts, under "ball joint" and others, but this may be different. My Liberty, w/ 42K miles, makes a seemingly random "grunt/thump" sound.I originally thought it was the rear tire brushing up against the tire well when turning in the parking garage. Then it happened when no turns were involved, so I thought it was the rear wiperblade moving against the dry windshield when hitting a bump in the road. Now it makes it randomly, even when stopped. It doesn't seem to do it at higher speeds. I've had my ball joints replaced, and it made the noise both before an after. I think it comes from the rear, others think it's from the front. Sounds like rubber against something. All else seems to function fine. Any ideas? Sorry for the long post.

    Have your tires checked. First run your hand over the treads and check for uneven wear. It may be a belt shifting in your tire. Use your spare and replace one side at a time. Drive it for a week with the spare on each side. If the sound stops the tire removed is the bad one.
    Good luck.
  • Hmm...I'm not sure that's it. Tread is evenly worn, for one. It sounds like rubber going over dry glass -- or a squeegee on a dry surface. It last no longer than a second. Kind of like a short burp.

    okay, hopefully its not the same thing that mine is doing. i just had the ball joint recall fixed and then noticed a grunt noise similar to when you drive over the rumble strips on the expressway. (the things that wake up drivers running off the road) turns out my problem is the lock up torque converter on the transmission. the jeep dealership is going to look into it more tomorrow so i don't know exactly what the problem is. mine would only make the noise when i was going about 40-45 mph. close to 42. i have 38k miles and evidently was supposed to have the tranny fluid changed at 30k-didn't brush up on my manual-oops. but maybe you should have your lock up torque converter looked out...maybe there should be another recall if there are a lot of these happening on the jeep liberty? cuz i know messing with the tranny stuff is going to hurt me in the checkbook dept. good luck to you :sick:
  • At idles in the garage, start turning on ALL of your electrical "stuff", lights, fan, radio, dome, rear defroster, and see if it makes the sound. My alternator went bad shortly after the belt tensioner went bad and was replaced. You sporadic noise may be because the alternator will kick on only when it is needed. BTW, in my case, the alternator tested fine and the battery tested fine when hooked up to the machine. But when the tech LOOKED AT the alternator, he could stand than and watch it bobble and torque on its mounting bracket.

    Good luck,

    I was in an accident two weeks ago. T boned some one that pulled out in front of me. Airbags never deployed. Has any one experienced the same problem or heard of an airbag issue in the 03 Jeep Liberty? Between this issue and the ball joint problem.....I am afraid to continue driving the vehicle.
  • I'll definitely check into both of these. The sound is primarily at lower speeds, but I think it has happened once or twice at 30mph+. Sounds like I have a duck under the rear wheel wells or something.

    chstockd, sorry, no experience (yet, thankfully) on the air bag thing.

    Airbags are designed to deploy when necessary. Since they did not deploy, you probably did not need them and they would have done more harm than good.

    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?
  • 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.

    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.

    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 2002 Liberty with 39,000 miles and I experience the same problem when turning into a parking spot, but not on a highway. A "whirring" sound followed by the grating sound you described. Any ideas guys? I recently bought my Jeep certified pre-owned, and I would like to have the work done before the warranty expires.

    Thanks for any help....
  • 02 liberty sport with 100k starts right up.But when temperature is below 30degrees it whines for a few seconds or sounds like a reving turbine fan. the colder it is the longer it makes the sound, but never longer than 10 seconds.nobody has a clue ,any idea on what the problem is?
  • hi, i have a new problem w/my liberty, ive already battled the flashing lights prob..still ongoing...
    i won the heater battle though....

    so now when i shift from Park to Reverse and start to back up i get this loud, hard bang. like something is stuck?????

    its so loud and hard that others in parking lots actually look!!!!

    side note: i feel like my e-brake is sticky too after i went to a drive-thru im afraid to use it now...
  • Hey, I was wondering if you got a professional response about the noises your 02 Liberty makes when you reverse???

    My 04 Liberty has the same problem and my dealer isn't giving me and answers..

  • I was wondering of any other 04 Liberty owners have experienced this problem.

    I hear and feel a vibration and grinding noise in the rear end of my 04 Lib when I’m turning a corner or reversing at low speeds, it almost feels as though my e-brake is stuck or on, which it’s not...the dealership where I bought it, not even 2 months ago, said that they can’t find anything wrong. It’s really annoying and embarrassing because I just bought it...

    Also, it has brand new brakes all around so thats not it..

  • Did this problem exist before the new brake job? If not, then you may want to have the brake job checked.
  • Hey all! My first time here. I have a 2005 Liberty and am getting a constant "Whine" when I press the gas. It has just over 100,000 miles on it now. The sound seems to be coming from the AC compressor. Any suggestions? I was told by the dealer it might be the tensioner or the pulley.
  • I have a 2006 liberty with 51k witch I in joy very much. resented I started to hear a rubbing sound on my right front wheel. I hear it when I go over bumps and when I
    come to a stop and when I turn the steering wheel left and right I jacked
    it up and checked the ball joints and every thing looks to be fine. I also put on the spire tire but the sound is still there HELPI don't have much money at the moment to take it to the shop and I really like the Jeep very much but that sound is driving me Crazy!!!

    You most likely have "posi-track" in the rear differential, my friend had the same noises, more posi-track additive in the rear diff fixed it. (Proportion of additive to gear oil needs to be higher.)
