Jeep Cherokee - Sqeaking Undercarriage

I have a sqeaking noise coming from the undercarriage of my 2000 jeep cherokee sport. Can't tell if its the front or rear. It only squeaks when the car is moving. The squeaking gets louder when I speed up but the sqeaking doesn't speed up. The colder it is, the worse the sqeaking. The squeaking decreases after driving 20+ miles. I had it looked at and was told one of the u-joints was bad and had it replaced. $200 LATER AND I STILL HAVE A SQEAKING NOISE! I figure its not a belt because it only happens when the car is moving. I went to grease the front end and noticed all the bushings on the steering linkage, stabilizer bar, etc. are all dry rotted. Could this be the problem. Oh, also, its not the brakes as they were replaced recently. Thanks

I have the exact same problem, cant for the life of me pinpoint the problem. i dont think its the belt or tensioners because it remains constant regardless of speeds over 15-20mph- does go away under those speeds though. especially bad when cold or wet, non existent when weather is good. very annoying. you can only hear it when driving- cannot simulate it when idiling or pulling throttle cable when in park.

If the "sqeak" is more pronoused while going over bumps, then it is most likely a bushing in the front end. Check your fuel tank straps also, they may be loose. Sounds like this are always a pain to locate. Make sure nothing is in the back cargo area. You can also take your foot and shake the exhaust, WHILE THE CAR IS COOLED OFF OF COURSE.
You can also push down on each corner of the vehicle in the front and stand on the rear bumper to try to simulate or isolate the noise. That's all I have for ya. Good luck.

Sand blast the rust and treat with several products they will arrest the rust. There use to be a product called TR7 and NAPA has a rust arrestor, then I would paint and or undercoat with rubberized undercoat. Make sure you start way from wires and fuel lines and exhaust areas

A rotational mid range sqeaking noise is coming from dash or engine. Occurs just after I reach 21 mph. Sometimes it happens, sometimes it stops after stopping

Just curious, check the cable under car near transfer case and see if it's rubbing on front driveshaft. If it is just loosely tie strap it to transfer case out of the way.

Check the transmition fluid level if you know how. The Jeep should be looked at by a mechanic as soon as you can do it. Check for fluid on the undercarriage that may be from a transmition leak.

I have a sqeaking noise from the front end. We thought it may be a u-joint, but the service center checked it out and could not find it. U-joints all checked out OK. Located in WI. The colder it gets, the...

Even if the joints appear to be OK, often they run dry and are rusted inside. Unfortunately you cannot see that unless you remove the axle and visually check them out.
You have universal joints in there? I thought they began using c/v joints right around 2000. Check that the brake pad sensors are not hitting the rotors as well that can make a squeaking noise.Before taking anything apart, try to determine which side the noise is on.
