Clutch noise with pedal down?!?

[etherpool]

First, I did search but not much came up.

I've got a 99 ti and yesterday started noticing some light grinding sounds when I held in the clutch pedal. Sound starts as soon as I press on the pedal and remains until I release it. Sounds like a throw out bearing but wanted some opinions. I also noticed that the pedal feels notchy when I release the clutch. Ideas??

I had the same issue when I first bought my ti..throw out bearing was bad. Your clutch might be worn out also..
Might as well change the clutch if your goin to be taking trans apart..
That's what I did and no more problem..G/L

yup, throwout bearing would be my first suspect too.

DAMN THAT SUCKS!!!

Sad thing is that this car had the clutch replaced back in 06 about 75K ago.

On Friday afternoon (6/18/2010) I pulled up to work and the clutch started to squeal. sounded like a belt but slightly different, as it only happened when the clutch was depressed. I drove home, and when to work the next day and it ran fine though all gears. When I got to fill up the gas tank, I heard it squeal but then it went away. After starting up and pulling to the light, the clutch would not engage. NO WAY, I could push it in gear. So I had to sit though the light(lucky no one was behind me). After 15-20 seconds I push it back to first and it went into gear. Drove maybe 5,000 feet. and each gear had issues but they switched for me so I could pull in work. the car has (218,xxx miles) So I'm gonna replace the whole clutch. But my question is wheather it could be the master/slave cylinder? or even throw-out bearing? I started it today and I could run (in gear clutch was working) and the squeal was still there but after 2 mintues of running it stopped squealing and then started to smoke under the car. This is when I noticed some kind of metal smell and I found it right near the transmission. It smoked and when I got into the car to move though the gears the clutch was now really strong and hard to depress the clutch all the way. My main concern is that the car had a good amount of build up of oil/gunk around the transmission but it never dripped so no need for concern(right). But that area either got so hot it started to burn or something else.(not sure) had the car for a whole year with not a single problem, almost 10,XXX miles since july 09. So I can't complain, any help would be much obliged. thanks Bryan

75k could easily be due for a new clutch, especially if they didn't surface the flywheel, cheaper replacement clutch was used, driving style, etc. Sounds like TO bearing to me..

I'd say if the clutch was hard to push at some point, that it's probably not the hydraulics and probably the TO bearing came apart.. show some pics!

MY car has manual Transmission Fluid???

So I did kill my clutch, and the worst part is that I could have prevented it if I had checked the fluid when it was squealing. (if only I had known)

I got the kit on its way from bavauto, now to find somewhere that will do the replacement cheap.

Hey ... You live You learn.

[Junk]

Huh? the fluid has nothing to do with the TO bearing. Don't worry, ya didn't do anything wrong..?

[tiFreak]

yeah, you're good, my standard transmission ti takes ATF according to the owners manual, I changed the fluid with Redline synthetic ATF and it's been running fine since

Make sure you replace the throwout bearing guide tube as well. It doesn't necessarily come in the kit.

I just called bavauto and Dan said that he never heard of such a thing. He explained to me that the TOB mounts w/o any other guide tube. I'm letting a buddy of mine fix my baby up.I got the clutch kit for $400.00 and the labor for the install will be $400.00 I consider that a deal, as far as taking it to the dealer they would charge me over $2000.00 Fingers crossed that everything works out and that I only damaged the clutch and not my Transmission. And have her back on the road by july

It's part #2, you have to remove it to replace the input shaft seal. which you should change out while you're in there anyways.

Check out Pelican Parts, read their do it yourself guide, it will explain just about everything you could possibly need to know about a clutch job.

The guide bushing for the throwout bearings becomes worn along the plane of movement of the bearing itself. if it's scored badly, the throwout can bind against it, causing grinding noises while depressing/releasing the clutch.

Its is possible to leave the original guide bushing for the TOB, my guy is gonna pick it up tonight. I just don't what to wear down the new parts because of not replacing the TOB guide tube.
I'm kinda PO, Thought the guys at Bavauto knew what they were talking about. I asked them 2 times now if the clutch kit has EVERYTHING I need. IF I need to get the part to make it run right, I have to drop the cash.
Thanks for all the help you guys, really helping me in a pinch.

[blndweasel]

well, yeah, my recommendation would be to simply change the orientation of the TOB guide tube by 90 or 180 degrees, this way the wear marks won't line up with the friction points, and you'll get some more life out of it.

it all depends on your definition of a complete clutch job.

I personally liked Pelican Parts's walk through. Their deluxe kit included:

Flywheel seal, transmission input shaft seal, shift selector seal. and of course, pilot bearing, TOB, clutch arm pivot and spring, clutch, bolts.

the guide tube was of course the one thing NOT included in the package. which is why I mentioned it to you. It's not an expensive part, so, while you're in there, you might as well... one of those arguments.

Alright I'm gonna order the part through Pelican parts now. If it could extend the life of the over all unit. My buddy never came though for me and I need to get back on the road. I want to thank everyone for there help, I'm still new here and I'm glad to know my Brothers out there are helping each other out.
When I get it in the shop on monday then I will update if there are any further problems with the transmission and such.
