Weird noise
 

Ok so when I'm driving I am hearing a noise coming from the front middle to left of my jeep. The best way to describe it is if you were to put a large nut on a smaller bolt and spin it (haha don't laugh). The noise is constant and I have checked the following so far:
- all fluid levels are good, changed front diff oil
- noise is constant even after shutting the car off and coasting
- noise still occurs while in drive or neutral
- noise is not affected by braking
- noise is constant while accelerating and decelerating
- when car is stationary no noise, happens at or about 20 mph and up
HELP!?

Additional to my original post, noise also occurs in 2 and 4wd and the t case in neutral too

Well, it seems like it's something to do with the drivetrain components if it only happens in motion. It could be a number of things, wheel cylinder, wheel bearing, axle shaft, transmission, transfer case, front drive shaft. Start by checking the brakes and rotors and all that, check to see if the front driveshaft has play, check anything else if you know how to. I'm not a specialist, but at least I can try to give you an idea and get you thinkin. I just hate when people post a question and don't get a reply quick enough. I'm sure this post will make it a little more noticeable to the experts. Good luck to ya.

^^x2. Brakes, u joints, wheel bearings. I'd start by chalking it, putting it in neutral, lifting and spinning one tire at a time

Thanks fellas for the input, I'm gonna try to crawl under this thing tomorrow and attempt to find what is the cause, Ill post up my findings here shortly...

Good luck!

any updates?

Yup, climbed underneath it and checked things out. The u-joint on the front drivers side has some play, ordered new ones for the front hopefully it will be the fix! Will update after installation

Sweet, good to hear that!

Just realized I never posted an update, I checked my front driveshaft which had a little play so I took it off and no more noise and the vibrations are completely gone. New u joints was the solution , thanks for the input guys !

No prob! CF is just like a family, we're here to help each other out.
