Strange Rattling

I'm back again. Different issue this time. I've been hearing this strange rattling and clicking sound that I cannot seem to find.

I only hear it at low speeds. At 5-10mph, I'm hearing two different sounds. One that sounds just like metal washers tinging together, and the other is a clicking sound. The clicking sounds reminds me of the clicking that comes along with a worn CV axel.

The bizarre part (to me), is that both sounds good away after engaging the factory lockers.

I have been under the jeep several times trying to locate the source, but have not found anything.

Does this make any sense to you guys? Where could this be coming from?

On a side note: Is the official JeepForum android app no longer available?

I don't know what it is, but my '06 LJ Rubi (stock, 33,000mi) is doing the same thing. The noise is not related to engine RPM, but is a function of Jeep speed. It starts off with no noise, then at about 10-20 mph it starts. At about 35-40 mph I can't hear it anymore.
When you find out what it is, please let me know.
Thanks.

Right. That's exactly what I'm experiencing. As I'm coming to a stop, the clicking seems to begin, and the speed of the clicks are in sync with wheel rotation.

The "jingling" sound, I haven't been able to relate it to anything.

Anyway. Hopefully someone who has figured it out can chime in. I will update if I come up with anything.

I told you guys wrong. The noises stop when 4WD is engaged. Regardless of locker engagement. So, I'm assuming something in line with the front driveshaft, or something within the transfer case.

I found the source. It's the front u joint.

Going revive this post with a new question. I did end up changing out the u joint which was worn. The high pitch noise stopped, but I'm now hearing an occasional popping type sound that happens on two different occasions.

One is when I'm coming to a stop. I'll occasionally hear a rhythmic popping sound that's in sync with the reducing speed.
The other time is when I'm moving along slowly over uneven terrain, with this one it's more of a single pop, more of a thud really.

The popping sound is nearly identical to a worn cv axel. I moved the front drive shaft just as I did in the old video and I'm seeing quite a bit of slop between the splined ends. Maybe 1/4" of play overall. The majority of the clanking noise in my old video is coming from this same point.

How much play should there be? It's OEM with almost 140,000 miles. When I changed the u joint, the original rubber boot was torn a bit, and I see now that it couldn't hold on for long, and fell off at some point.

Seeing the u joint from this angle makes me think that it's shot again. Maybe all of this play in the driveshaft wore the u joint out?

I've never seen a driveshaft with play like that before. I wouldn't be surprised at it wearing UJs.
