When I release or depress the clutch pedal, I can feel a very subdued "clunk" or "pop" at two points in the travel.

This only happens with the car on, and it happens in neutral or in gear. I hear talk of input shafts not being lubed enough or bearings catching. My real question - is this hurting anything?

It doesn't seem to do it when its warm outside....actually, it doesn't do it at any discernable interval I can think of- just whenever it feels like it, I guess. I drove the car earlier today- nothing. I drove it to work -popping pedal feel. If I let the clutch out very slowly, it wont do it and I seem to be able to stop it if I put pressure on the pedal at different angles.

What is going on here?

 

try bleeding your system. i had clutch problems while back and it ended up being my slave cylinder, but i ended up replacing the master cyclinder while i was at it too.

 

Its a cable tranny. Do they still have things to "bleed"? I have no expertise with tranny's

 

no they dont bleed. i wasnt aware you had a cable tranny. maybe your line is... pinched or sumtin.

 

doesnt happen at all when the car is off.

Even if its in nuetral...so long as its running, it pops. As soon as I turn it off....smooth as silk.

 

up for help

 

c'mon, ideas?

 

that just aint hittn me man... where does the popping noise come from? hey i got to fix my throw out bearing so ill be gone all day. peace

 

The popping SEEMS to be coming from the pedal mechanism itself- the first thing I did was get under the dash as lube it up....no help.

Something isn't adding up with that theory though since it only does it when the car is on.

If I can feel it so profoundly in the clutch pedal- if its not coming from the pedal/return spring- then it must be a HUGE pop inside the clutch housing to send a vibration that big through the pedal, agreed?

 

ok, I tried some things out

1) goes away or is unnoticeable at high RPM and/or heavy throttle shifting.
2) seems to go away under turning - axle?

I still would like some help figuring this one out.

how old is your clutch?
springs in the disk comming loose?
I dont think its bearings since it would affect driving(or at least hear it)

 

I have the same thing in my car and no one seems to know what causes it. It's like a mystery, haha. But mine is a hydro tranny tho. It happens on and off like you described it but instead mine can happen with the car off too so I'm assuming that it might be the throw-out bearing sliding on the input shaft without adequate lubrication. Either that or overtightening the pressure plate bolts. When I installed my clutch, I just tightened it until I felt it was good. I didn't think that 19lbs of tq. would be that crucial (if that's even the cause of the "popping").

In your case, I think it may have something to do with your clutch assembly when it's spinning. Since you said it only happens with the car on.

clutch is a fairly new (not yet 10k miles) clutch master stage 3 carbon/Kevlar unit.

Said to last a long freakin' time.

Ill have to get the guy who did the swap look at this, its only been like 7k since he did it, and hes my fiancees uncle (mauahahahaha) who happens to be a Honda mechanic.

Also, lets not forget that it doesn't do it unless the clutch goes all the way down, then it will pop on the way up. If It goes 3/4 of the way down, no popping. Almost like it has to hit a "snag" at the bottom of the pedal travel, then the snag pops free once I get it nearly to the top of the pedal travel.

I can also let the clutch out REALLY slowly and it wont happen.

That's how mine is.

 

Ive already e-mailed ClutchMasters about it, no reply as of yet.

mmuller mentioned the hub springs....that sounds like a real possibility.

 

Its very cold today and im noticing that upon take off, I hear a groaning/creaking from the axle/tranny area. This is starting to really worry me.

 

sounds like your's is a lot worse than mine. mine is more of an annoyance. it hasnt messed anything up ..yet (that i know of). i've tracked/dyno'd/spirited driven in the car with the clutch pedal like this.

dunno what could be wrong with yours. good luck on getting it resolved.

 

I can slam the gears and drive it like a hate it, and it seems no worse for the wear, and the groaning only happens when its very cold (its 0 degrees here)

I know I need a new axle, the inner joint is bad- I think that may be to blame for the groaning. I had to throw it out there in case someone knew if they were related.

On a similar note, since you have a hydraulic system, its probably the clutch cylinder. I hear they make the pedal "pop" when they start to leak. Of course, that knowledge doesn't help ME any

 

Just talked to the owner of the shop I go to, he said he's almost sure its a throwout bearing catching on something. He told me its not a big deal if everything is still working fine, and its most likely just due to the severe cold. He especially thought it was the TO bearing when I told him it doesn't do it when the car is off.

Ill wait until it warms up, its its merely a cold weather annoyance, then ill just deal with it.

Does this sound about right to everyone?
