Weird noise.

Does anyone know what could cause this noise?

My mechanic said it was the front differential but when i went to a jeep shop they didn't think that was it.
Also if it is the front diff is it safe to drive on?
Thanks.

Kinda hard to hear in the video, if I'm supposed to be hearing that clunking noise every few seconds I doubt it's the diff. Easiest way to find out is to drain it, pop the cover off and look inside. At worst you find out it's something bad in there and if not you get fresh gear oil and a fresh seal around the cover.

It's the loud humming noise that you can hear throughout the video. I'll try checking inside but have almost no mechanical knowledge.

Can't really tell whats what from cell phone video, but then again I'm damn near deaf.

If you can turn a wrench you can open the diff up. Put a drain pan under it, unbolt the bolts, hit the cover with a rubber mallet after it stops draining and take it off. At that point you can look and see what's going on there. Diff problems are usually pretty obvious. Chunks of metal missing, gear tooths missing, shavings in the diff fluid, ect.

My Jeep can sound something like that when the oil is low somewhere.

Are both front & rear diffs filled? Is your transfer case full?
When you open the filler plug on the front diff, are there any metal shavings
sticking to the back of it? My 98XJ has a magnet on the back of the plug.

If you recently bought this Jeep and you don't know the service history, it is
a good idea to change all the fluids and fill with factory recommended oils/fluids.
The PO might have put the wrong oil in something.

The noise might also be a front wheel bearing/hub. They can sing like that. Does the
noise vary a bit if you steer left or right? Jack up each front wheel, grab it, and see if
there is any play at all in the hub.

Bottle and a half of 80w90 or 75w90 gear oil. Stay away from synthetic.

Try to keep it off your skin too. Won't hurt you but it stinks and it sticks in there. Only thing I've ever found to get rid of the smell out of skin is bleach.

So i took the cover off today and this is what i found. http://imgur.com/88scKbO,JxvHHNq,EMGtvnP,XZvEGNg#0 From what i can tell everything looks alright im just letting it finish draining now. The plug does look like it had some metal on it but i wiped it and they don't seem to be shavings.

Was that the frint or rear diff? Also if you still have the cover off, take a picture of the spider gears and rotate the carrier too that way we can see as much of the diff as a picture will show.
