A concerning noise...

I just bought a 2006 TJ from a dealer last weekend. Its the Golden Eagle trim, 4.0 and the Dana 44. It was essentially bone stock and had 33k miles on it. I drove it and listened to it and it sounded pretty legit to me. I ended up paying more than I expected but it was tough to pass up such a good looking jeep just the way I wanted it. After I drove off the lot I realized I heard a noise that was a little bit concerning. Its kind of like a high pitched clicking sound. It doesn't really get louder, but I can definitely hear it click faster when the rpms go up. When I get into 4th, 5th, and 6th gear I can barely hear it which I assume is attributed to just the rest of the noise covering it up. Today I experimented and if I press in the clutch it goes away; even if I rev the engine. But if its in neutral and I rev the engine I can hear it. I saw a couple earlier posts about the 11th lifter and arching. I looked under the hood while it was dark out and the engine was running and I didn't see any arching. Can anyone help me? The car has a warranty so I can go back to the dealer and have them look at it. There is also a Jeep dealership right down the road from me and I thought maybe I should just take it in and have one of them look the whole thing over. I would really like to do most of my own work on the jeep but as I am new to this it may be tougher than I can handle at the moment. Any help would be awesome guys. Thanks.

If is goes away with the clutch depressed... sounds like it could be coming from the throwout bearing... mine always makes noise when it's out in neutral.

i would look at the clutch slave cylinder to see if it is just the plastic retaining strap
that holds the slave depressed until installed and then snaps to release the plunger.
i had one of the straps slap the clutch and make a ticking sound that drove me nuts till i figured it out

The throwout bearing only works/spins when the clutch is depressed. A bad throwout bearing will tend to make noise when the clutch is depressed.

What you hear when the transmission is in Neutral and you are not stepping down on the clutch is the sound of the transmission's input shaft spinning inside its bearings. The engine is always spinning the transmission's input shaft unless you are stepping down on the clutch pedal.
When you have a choice, buy American.

My buddy took a listen to it today and is also under the impression that it is likely a bearing. Him and I are going to replace it ourselves.
