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.
