I have a sound when I am sitting still at a light or stop sign or something like that but it goes away when the clutch is engaged. It sounds like a kind of rubbing or shaking. It seems to get a little louder when the car is warm but it always goes away with the clutch engaged. I'm lost on this one.. any ideas??

 

I think you mean to say dis-engaged (pedal depressed) , but anyhoo, sounds like a worn throw-out (release) bearing.

 

 

when i am holding the clutch pedal in.. thats engaged right? it makes the sound only when im not holding the pedal in, it goes away when i do.

 

Clutch engaged means it is spinning the pressure plate and your foot is off the pedal.

I agree with everyone else, sounds like the throwout bearing. Anytime the clutch is replaced, the throwout bearing should be too. Doubt you have an origional. Someone skipped a step and now you have to pull the tranny just to fix it. Not your fault, it's the nimrod that did the clutch last.

 

I forgot to mention that it could also be the piliot bearing in the crank or the main bearing in the tranny. Those two are unlikely but it can happen. Most likely it is the throwout bearing.

 

sooo.. who wants to show me how to replace a throw-out bearing?? beer is on me

 

Not too hard if you've got a good place to work some jackstands/jack and some mechanical aptitude. I pulled the T5 out of my GTA in a little over a hour.

Jack up car high enough to pull transmission out, support engine with jack/wood

Unbolt driveshaft from yoke (mark it so it doesn't go back 180 out)

Slide shaft out of transmision (have catch pan ready for fluid)

remove x-member (make sure engine is supported well!)

unplug connector(s) from tranny

take out 4 bolts that hold tranny to bellhousing

pull out transmission, (I did it by hand and I'm pretty much a scrawny wuss but if there's any doubt get some help and/or jack)

remove bellhousing/clutch fork/ball stud, etc. bearing is in end of fork

Now is the time to at least visually inspect pressure plate for broken, worn, missing fingers - but do not unbolt it unless you have an alignment tool handy (also don't dpress the clutch pedal with the tranny out or you'll need aforementioned alignment tool)

lube up new bearing

installation is the reverse of removal.



PS: I noticed you live in Dundalk, how's that 3rd gen suspension hold up to those roads?

 

Lets just say 3rd gen suspension + sub-frame connectors + traction bars = no fun in the bumps.

As for the throw-out bearing, I am having some tranny work done so I'm just gonna buy a new one and have them install it then.

 

I hear ya, I was down there about a year ago meeting up witha friend of mine, I hit a pothole on Dundalk Ave so hard I smelled coolant for 5 minutes and then it went away, never did figure out what it was but it was in my daily driver pos Celebrity so I just left it go, lol.

Sounds like a plan with the shop too.

 

there was a tech article on this before, everyone thinks that the throwout bearing is bad, but it is not. when you press in the pedal and it starts make noise, then yes its the throwout bearing, but if it makes the noise constantly, and stops when you press the clutch in, all it is.... it needs lubrication, the bearing is rubbing on something, and as soon as you put pressure on the pedal it removes it from what ever its rubbing on. get some spray grease and remove the clutch fork boot from the bellhousing, and look up in there and you will see the throwout bearing and spray some grease on it. cant hurt to try, alot easier than changeing the thing when its really not needed.

 

Maybe Im wrong but if it was the throwout bearing wouldn't the noise be heard only when clutch pedal is down. (When release bearing is up against the release fingers?

 

If it's anything like mine was it just sort of made a vibrating/whirring sound right after I let the pedal out and occaisionally at idle or cruising at low rpm like it was still spinning, loose, or vibrating. Depressing the pedal I think just puts enough pressure on it to keep it together so to speak.

 

Nope. As Cooper has said, it would be taking the slack off the bearing and quiten it down.

I have a different kind of problem. I replaced my clutch with a new unit. That straightend out a few things. Then I had the T5 rebuilt. It works fine.

There is one exception.

When it is hot out and the car is fully warmed up, when the clutch is let out in first gear it viabrates really bad. When fully engaged it is fine. Fine when cold. Even fine during the winter when the car is warmed up. The pilot bearing was not replaced when the clutch was replaced. Tranny guys told me it should be fine based on my millage at the time. I don't think it's fine. This was rebuilt about 6 years ago and I avoid stop and go with it ever since. Seems smooth otherwise.

Yes I can drive a stick and not overheat the clutch. I can cut 2.00 short times with street tires on the drag strip. Passengers don't spill their coffee unless I want them to! Me thinks it's the pilot bearing since it's the only thing left. Anyone have an opinion?

 

My problem exactly. I'm all ears for a fix.

I'm shocked. Never ran into anyone that could provide an explanation before. They all looked at me as if I had two heads. Mostly folks who rebuild trannys for a living. Hope someone here has an explanation for that one.

 

that is exactly right.

 

Did you re-surface the flywheel?

 

Yes the flywheel was resurfaced. The tranny shop I bought the clutch from was even kind enough to come pick it up, and bring it back to me after resurfacing. I did the swap in a back alley. This was back in the days before I bought a house. It was a strange day and lots of weirdos in that alley. Was getting a little worried when the sun went down.

 

Myself and JamesC would love a explanation or even a thought as to why our symptoms would happen.

HalfInch,

The fork boot had pulled away from the bellhousing--perhaps as a consequence, the grease on the pivot ball had pretty much solidified into grime. I loaded a finger with grease, swabbed around on the ball, and properly installed the boot. So far, no groan, no vibration. Cheap fix too
