Clutch question

Hey guys , just wondering what this noise is I'm hearing. The noise is most noticeable after the jeep is warmed up.It makes noise in neutral with the clutch engaged only and makes quite a bit of noise if you let the clutch up to just where it grabs in gear but stops when fully engaged.Is this the throw out bearing? Thanks for any input.

Do you mean it stops when fully disengaged? You said further back in the same sentence that it makes noise with the clutch engaged only. If so, it most definitely is your throw out bearing or a bad pressure plate, both of which are clutch parts so it really doesn't make a difference which one it is.

Yea sitting in neutral with the clutch engaged it rattles.It stops when you push it in and is really noisy if you put it in gear and let the clutch out to the point of just grabbing.

I'd just do a clutch. New T.O. bearing, disc & pressure plate. Machine the flywheel. You'll be in good shape. Oh, and do the seals to while your in there. Just me but I'd use a Center force Clutch set up. They make clutches for everything and you can buy the setups for the way you drive. Like off road, drag racing, normal street use, etc.

Sounds like clutch time. If you do the work yourself, you can get a LUK clutch kit for a 4.0L for $93, and seventy something for one for the 2.5L at Parts Geek here: 1994-1995, 1997-2006 Jeep Wrangler Clutch Kit - LUK 05-065 - - PartsGeek.com

Do not have the flywheel machined. Flywheels on our Jeeps have a slight dome shape that machining gets rid of. Just hit it with a little emery cloth or sand paper, or if it is heat checked bad, replace it.

The throwout bearing is not spinning until you step down on the clutch pedal which engages it. A bad throwout bearing will get noisy when you step on the clutch pedal, not when the clutch pedal is up.

Also, it is 100% normal to hear noise from the transmission when the engine is running, transmission in Neutral, and the clutch pedal up. In that configuration, the engine is spinning the transmission's input shaft and bearings which is loud enough to be heard through the Wrangler's near total lack of soundproofing.

So now I'm confused is it the pressure plate then? It is a 4.0 the jeep has 120, 000 on it I've only had it for 6 months so I don't know if it is original or not.

Trying to figure out exactly what is bad is not really helpful since a clutch kit includes the clutch disk, pressure plate, pilot bearing, pilot shaft, and throwout bearing. Whatever's making noise will be replaced by what's in the clutch kit. I strongly recommend the standard Luk clutch kit, and not Luk's more expensive Gold kit (meant for trucks) which is noisier than most would appreciate.
