Hey guys,


Just last night randomly I heard some noises like clattering with the clutch pedal IN only. So I was like hm funny, then all of a sudden the car randomly wouldn't go into gear, again I was like hmm funny. Then on the way home, when i pushed the clutch in, it wouldn't fully catch and the car would like bounce forward. So anyway, does anyone know what bearing is bad?


Im thinking if its the throw out bearing it would make noise with the clutch depressed, but my car makes noise only with the clutch pressed so... ??? Anyone , rynberg do you know ?

Could also be a bad pilot bearing.

yea my fault I ment pilot bearing now shaft bearing lol

alberto_mg

search for clutch fork

betcha that is what it is.

see so I have 3 different things It could be. Im going to pop it down in the next few days but , this morning I drove it and it was fine cept for the noise .... hmmmm

When you press on the clutch pedal, the hydraulic slave cylinder presses the clutch fork. It deflects the clutch mechanism. Because the clutch is turning a bearing is needed - the throwout bearing. The clutch fork can break - it's happened to several posters. The bearing can also fail - either it wears loose or seizes and makes lots of noise.
The slave cylinder and even the master cylinder can also fail. Put the car in gear with the clutch engaged. Slowly release the clutch - it should smoothly slow down the engine (e-brake engaged). That should tell you the hydraulics are ok. Put the car in neutral. Let the transmission spin (clutch pedal out). If you hear noise, it's the transmission input bearing. Depress clutch. If you hear noise it's the clutch mechanism - either the fork is failing or the throwout bearing is failing. The pilot bearing doesn't fail very often, but only spins when the clutch pedal is fully down. The throwout bearing will make noise when you depress the pedal slightly.
You should get a better idea of what is wrong going through this method.

If your throwout bearing is starting to go and you disregard the noise, it will start to eat away your clutch fork untill there is nothing left..

I just had a new clutch installed by the previous owner and it has about 1k on it.

david, your right, it only makes noise with the clutch pedal DEPRESSED.. so its clutch related.. im thinking the TOB or the Fork, but like i said i drove it today with minimal problems other then the noise. It is going to be fixed this week thou, I assure you not

My crystal ball says clutch fork. (g)

Well think about this also, when the pedal is depressed, the flywheel and pressure plate continue to spin and the input shaft and clutch disc stop... so the input shaft is now reliant on the pilot bearing to keep from spinning. If the pilot bearing is bad, it will cause the input shaft to want to spin even if the pedal is depressed and the clutch disc is not in contact with the pressure plate and flywheel ie. the car still wants to pull if it's in gear even if the clutch pedal is depressed.

so let me get this straight if you hear a spinning noise while in neutral its your input shaft? is that correct?

My vote is for the Pilot bearing or clutch fork. I've had both fail with similar results (although the pedal will feel springy if it's the fork).

I experienced a similar noise and occasion "catching" when my pilot bearing failed--that is until all of the needles fell out and it cleared itself. And I drove it for a long time (a couple of years) after the pilot bearing was gone without any difficulties.

I doubt its the clutch fork ... but what would make the car occasionaly not shift ? Thats what I dont understand. If it was the TOB then I dont think the car would have a problem shifting, just make noise when the bearing is engaged. Does a bad pilot bearing make the car not shift right ?

Anything that causes the input shaft to turn after the clutch has been released can cause a shifting problem. If the pilot bearing binds, it will do this; if the clutch doesn't fully release because of a bad or failing fork, it will be hard to shift. In some cases, a damaged clutch face that causes a problem. I agree that it is probably NOT the throwout bearing for reasons you just cited. I still think the pilot is the likely culprit--I've had this happen once in my FD and twice in my FC.

yea im going to check through the inspection ports tomorrow and see if its the clutch fork, if not then it has to be the pilot bearing

icarus179

where are the inspecting ports???
My 86 GXL is doing the same thing I planned on doing the throw out bearing but.....

so has this been fixed? I have a similar problem, only i have no problems shifting into any gear. I only get like a scratching noise when i start moving from the dead stop. I can put it in gear fine, without any problems and no noise, but soon as i start releasing the clutch to start moving, it starts scratching until it catches on and then it's all fine. No other problems what so ever.

With the reality being that you are going to tear down anyway, the best course of action, at a minimum, is to replace both the throw-out bearing and the pilot bearing. I usually do the entire clutch assembly (friction plate, clutch cover, t-o bearing and pilot bearing) as the best protection from having to do it again right away. Make sure you lube the pilot bearing and the throw-out bearing. My last clutch was done by a dealer mechanic and he failed to lube the pilot bearing. Great!! At 25,000 miles it was squawking like a bitch. Needless to say, I did it myself this time.

nopistons94

hasn't been fixed the right way yet. We took of the inspection plate and noticed that the TOB had been slightly off the fork and we smacked it back on and haven't had the problem since with it. Still get the noise every once in a while, I think the fork is bent.

It may be the fork, but it may also be that the wedge collar and wire ring are not holding your t-o bearing to the diaphram springs securely. If they were not replaced in the last clutch job, they will almost definitely fail. When they totally fail, you will be stranded and unable to disengage the clutch.

Yes a bad pilot bearing will make it hard to shift or if in neutral not allow it to go into gear, when it locks up completely it will be hard to get the input shaft of the transmission out of the engine.

Not a 3rd Gen, but my Rx2 did that...push in and it made a horrible metal screetching sound....then started creeping forward.

Sorry to tell you...I'm 99.9% sure its your pilot bearing...and I hate changing those *******...especially if they're stuck.

TwinTurbo_SE7EN

ok. so how about if eveything is normal except a slight noise when the clutch is out (as in not on the floor)??

and it goes away once the pedal is pushed in.

Sounds like you may have something loose in your tranny or your TOB is loose... the input shaft spins constantly when the pedal is out.
