Okay, So I bought this wrangler a couple days ago, and it has a bad rattling noise coming from under the hood. So I did what came to mind first, Replaced the idler pulleys, and the rattling is still there, so I got up under the jeep and listened and it sounds like its coming from either the crankshaft or the CS Pulley, When I watched the pulley in action it has a slight wobble, nothing like the idler pulleys, but it moved slightly. The sound is a metal on metal kind of sounds like if you beat a wrench softly but fast on the crank case. When you take off in 1st gear sometimes it will sputter and sometimes it won't. Not really sure if that is relevant but I did research and it said that it can cause it to sputter at low speeds. And problem number two, My 2nd gear and Reverse are hard to catch, and the clutch is spongy. is that a sign of a new clutch? Please help me I love my jeep and I need to know if it's going to get damage by driving it.
