I did not have the same kind of noise. Nor am I a mechanic at all! But if I had to guess by your description I would have to say it sounds like a belt issue. As the motor speeds up so do your belts that drive it. A cheap and simple way to test that theory is to go to your local auto parts store and purchase a bottle of silicon spray. and while your car is in park lift the hood and on the inside of your moving belt spray a little on it. The bottle will come with a straw for the nib of the can just like a spray bottle of WD-40 for accuracy when spraying. Just a thought. Good Luck and let me know if you had any!

Hi littlemissy442,
If you suspect a vibration in the steering at high speed plus a permanent whistle when you're moving, disconnect your alternator 'field' connector. When mine went, I could hear 'another whistle' or vibration around the engine. When you do this test turn the A/C OFF as well.
In case one or more rectifier diodes short out (inside the alternator), the alternator output will fight 'against the battery' and produce a sound you can interpretate as being a whistle 
Both alternator and a/c compressor are driven by the serpentine belt, so is the power steering pump. If your belt does not rotate at a steady pace, the steering assistance will vary as well.

Noises

I bought a used 2006 Jeep Liberty in February. Overall, it has been great. We had 4 brand new tires put on in March, no word about bad brakes from the mechanic. The car makes 2 or 3 different noises that all stop when pressure to the brake is applied. 1 noise is a louder, metal screeching noise, sounds like its coming from the right rear and stops when the brake is applied. It can happen at any speed, stop randomly and start again. 1 noise is a softer metal whistling noise which also stops with the brake and I think there is even a 3rd different noise but hard to tell. We also noticed a vibrating noise when the car has been shut off for a few hours. Just noticed it while working outside, it almost sounded like a cell phone vibrating but louder. It comes every 5 minutes or so.
Any help would be greatly appreciated.

I had the same problem on my 05 renegade. What you need to do is take it to a dealer or certified body shop, and have them adjust the latch that secures the gate to the vehicle when opening or closing. This should take came or the problem. I had to get mine adjusted 3 times. As i was just taking to around the block to test for the rattle. This was a common problem the dealer told me.

Rumble/Viberation on at 70mph

I have a 2005 Jeep liberty renegade. I have a rumbling noise and viberation around 70mph then it goes away and come back from around 83 up on. Does anyone have any idea as to what this could be? It seemed to start after I had the rear U-Joint replaced. So I think the U-Joint may either have a defect or is not in place correctly. Anyone else have suggestions or similar problems?

From the sounds of it, you have a similar noise to the one I have in my 2006 Jeep Liberty. I purchased mine in May '09, and after a few days of driving noticed the same piercing metal noise coming from the wheels. This only happens while the Jeep is in motion, and like yours, happens at multiple speeds, randomly starts, and stops when the brake is applied.
I have taken mine back to the dealer twice. The first time they replaced the rear rotors as they had corrosion from sitting on the lot (a fairly common problem according to a friend who is a mechanic). However, the noise returned after a few days. I have been told that the noise is a result of the metal pads and rotors used on the Liberty. However, it seemed odd to me also that the breaks would be squealing while they are not even applied!
Still searching for a solution...

kbeast1979. So I took the 09 liberty in and they told me the exact same thing about the flash updates and gave me some crap about the adaptive transmission? I can not drive it without getting fumed about it so it is going back tomorrow. I can at least pinpoint where the issue is this time. As soon as the tranny hits 4th (50mph), the low end has a pulsing growl, especially when a small load is put on the engine such as a slight road incline. It mostly goes away as I go faster but I can still hear it through 80mph. I would love to hear more about what Chrystler has decided to do for you because I am in the same unsatisfied boat that you were in?
Let me know, you can email me directly if you want.

mcarver82. Ok, well we weren't happy to say the least about how it was all handled. We took it in, they did the flash update, luckily she had a free car rental policy in her contract when my girlfriend purchased the car, gave her a car rental, returned the next day and they said they thought it was still doing it. She drove it and agreed. They said they wanted to leave it there and contact the Chrysler engineers to see what there thoughts were after replacing the front and rear driveshafts at this point. They had the car for 3 weeks until the 2nd representative could come out from Detroit and take a look at it just to tell us afterward that there was nothing that they were going to do about it nor would the dealer. They said that it was just something that was a characteristic of the vehicles for the 09' and 10' Liberty models. How many miles are on your vehicle? I later found out from a friend that knows someone that works at a Chrysler dealership that when that flash update occurs at the dealership the computer reads how you drive your vehicle after that point, shift more effectively and completely adjust itself at or right after 4500 miles. Hope this helps. I think we were one of the first to report it to Chrysler. So I hope that by now it has become more of a routine issue and they will know how to handle it better for you. I will say that the vehicle does not now have the issue and hopefully will remain that way. I will be keeping my fingers crossed for sure. I don't know how much of the issue was helped by the replacing of the parts that were replaced with even newer ones. (She had 3600 miles on the vehicle.) The parts were the front and rear driveshafts, and I believe the gear-box.
Good Luck,
kbeast1979

KBeast1979,Mine only has 950 miles on it? I did not want to drive it too much knowing what was going on with the vibrations. I got two people to ride along last night to ensure that they could pinpoint at what shiftpoint the vibrations start and stop. I at least got acceptance from the dealership that something was wrong. I'll keep you updated when I hear back probably today or tomorrow, and unfortunately they nor I have rental coverage if they decide to keep it for a while.
Thansk for the info.
