Rattling Noise

I have a rattling noise at idle but when I engage the clutch pedal it goes away, then when I release the clutch pedal the rattling noise comes back. I went under the jeep and it sounds like its coming under the transfer case. The only two things I think it could be is throw out bearings on clutch is bad, or maybe I should change the transmission fluid. It has 33k miles and its a 6 speed manual with the NV

The throwout bearing should have lasted alot longer than 33K. All manual transmissions will make some noise after awhile. I wouldn't worry about it unless the clutch is not disengaging and you are grinding gears.

I have got the same noise going on. Mine is also a 2005 with only 40k on it. How do you find out if any recalls are out there?

I just grind in reverse but someone said before I go into reverse gear I should throw it into 4th gear first then reverse.

I have a 2006 LJ with 62k miles I just bought used from a dealer. I hear the same noise at idle in neutral. I've read elsewhere it's a common issue on the 2005-06 manuals. Still makes me nervous.

I have the same issue (though mine is a 2000). There was a TSB back in 2000 about some kind of bearing making the noise. . . . maybe yours is doing the same thing. Its not anything that has to be fixed, just a little annoying at times. Turn up the radio

If you have your BL on, the shifter may be hitting the console. I had to move my console back 3/4 inch cause I grinded in 2nd and Rev due to the shifter hitting the corners of the console.

No I don't have the BL on yet.

Can anyone else tell me what this noise is. I just can't see how this would be normal. Automobiles can be like a human body when something is aching or hurting theres a solution to the problem.

Subscribed - 05 6 speed with 47K miles and I get the same thing. On mine it feels almost like a knock against the bottom of the tub at my feet. Mine is currently all stock except wheel and tires. The knock feels like the t-case shift linkage issue after the BL, but it's in the wrong place for that. I'm crawling under there this weekend to look for exhaust mounts or heat shield or tranny mount issues. If I see any external cause under there, I'll post it.

Have you checked the shock mounts? Have someone rock and bounce the Jeep as you go over everything.

I have it on mine as well. I have to think its the throw out bearing. When it gets too annoying to put up with ill deal with it. Some noises are just inherent to certain vehicles.

if it goes away when you push the clutch in....the only possibility is throw out bearing! Yes this is common (not normal) It just means the brg is either a little wore or dry! Very annoying yes....!

This may be a long shot but I had a rattling under my TJ and the Converter honeycomb had come apart internally causing a significant rattle at idle. I could literally rock the vehicle back and forth when it was parked and it would rattle. Your cat should not be coming apart at that low of milage but try getting up under your skid plate and tapping with a screwdriver to see if you can duplicate

Found my rattle, but it's not likely to help anyone else. I got under there and pulled and tugged on everything and the only 'knocks' I could generate were from the rotational slop in the front DS and the E-brake clevis where the front and rear cable join. I started the Jeep, put in in neutral and got under it again and heard/felt a faint mechanical knock on the oil pan and trans, but not on the body. As I was pulling myself out from under, I was face-to-face with my culprit....Rock slider frame mount!

See the photo below and the rust evidence of bracket to body contact, basically short cutting the rubber body bushing and allowing direct frame to body contact.



any clue who makes these sliders? her are a side shot and the mount detail shot.





There are two mounts like this per bar and only the front are making contact, on the outside of the frame.
