Yeah dude might as well get a clutch kit, flywheel or get yours resurfaced, and change what doesn't look good in the transmission. I thought this noice was coming from the ToB so I got an oem clutch with lightweight flywheel while I was at it. Ended up the my ToB was fine and It was the ISB.. had to pay to take off the transmission two times in one week.. Anyways got it there ended up that my ISB was totally worn out and had some bad syncros 2nd 3rd and 5th?? Don't know how that happened??? Guessing the guy that had the car before me was shifting hard in 5th.. doesn't reassure me that much but anyways.

where did u have the work done? id fight them (edit: for the cost of the labour to pull it again if need be), its easy to tell if the tob is damaged as well as to tell if the isb is teh problem. Not saying anything bad against the shop but they should have been able to pick up on that the first drop

sounds very similar to the noise i had...can you post a video?
not sure if this is the same as what u said i know this is older comment but, my tob was shot destroyed and i only heard the noise when i would shift was fine just driving or sitting in neutral at a light, this was soon after Mitsubishi apparently replaced it for me aswell

Well. I dont have any space to work on it, so id have to pay someone to do it also, but id buy the parts myself, I can get oem stuff cheap, and ill probably get that act clutch from rtm.

Thanks for the help guys, much appreciated.

it depends, i've heard TOB's make noise all the time (really ****ed), but more commonly it just rattles when not in use, once you put some pressure on it, it stops...

It was a lot quieter while it was on the hoist and im guessing thats because there is less load on the wheels?
your right from the outside like that it almost impossible to tell and most often is the tob, its not till u drop the trans that youll be able to figure it out

I drove the car until the TOB exploded in a thousand pieces... JTCB has seen it, it was awful.

It made a weird whine, almost like a supercharger, only when I had my foot on the clutch. Any amount of pressure on the pedal made the noise come back, but if I removed my foot from it, it would be completely gone.

It wasn't gear or speed related. It only made noise while my foot was on the pedal.

I could sometimes hear it while not on the clutch, but it was extremely faint, and happened rarely.

The TOB made noise while it was in contact with the pressure plate only. It is only in contact when you press the clutch pedal in.

RA TOBs should not make noise while at rest, as it serves no purpose at all and touches nothing except the fork it is attached to. This is valid for RA's, some cars have different TOB/pressure plate configuration which could change the symptoms.

If it makes any noise while you do not have your foot on the clutch, then it is NOT your TOB.

you can hear them rattle when they get loose...but yes, if they are completely ****ed, which yours was, since it was used until it exploded, i wouldn't be surprised if it made noise while in use...

it's hard to tell by someone's description of a noise unless you've tested all possible conditions and whether the noise is present or not present for each...

It slowly started jamming until it finally seized. It's a ball bearing, if it loosens, you will end up with parts falling from it and the pressure plate will probably tear it apart, which was the case with mine. Here you can see the sleeve, and how it got eaten by the pressure plate.



The pressure plate grinded on it until it bit in and shredded the whole thing. Here you can see the damage done to the pressure plate.



I cannot see how it could be loose enough to be noisy (loud enough to matter) and work still. Maybe a bit of slack on it's supports, but the bearing itself would still work... Imagine all those parts getting loose in the bellhousing... I couldn't do one more foot this way.



Also, as JTCB already said, if anything, it is the ISB. The TOB would only be noisy while pressure is applied on the clutch pedal.

It is not the TOB. The TOB has no connection to the gears of the car. It is working when the clutch pedal is pressured, and at rest when it is not.

Yup, you think it's the TOB even though OP clearly stated he only has noise while in gear.

Maybe you should explain to me how those two things can be related?

Yeah you should go into business and install my future turbo kit and that LSD!!
Um lets see cost me like 750$ with parts including the lightweight flywheel.
The second time the transmission rebuild cost me between 700-900 with parts. This was done by two different people. Also as I stated before I had the same problem and only the ISB makes noise when in gear. Ive seen a few cases of shot ToB and they do not make any noise when in gear from my experience.

i already stated i didn't think it was the TOB...so you're the one who missed something...i only mentioned the TOB when RalliartRob brought it up...good reading though

seriously, i've done my share of clutch jobs, and transmission rebuilds you don't need to lecture me on how it works...if i make an error, i would welcome a correction, but you obviously misunderstood something i said...
