transmission, pilot bearing or throwout bearing????

[cocolo]

I'm having problems with my car. Sometimes when I push the clutch pedal a weird noise appears, I have to push it a few more times and then he works fine. The noise sometime its very loud and I don't know what is it. I had searched and in some post says that its the transmission, other that its the pilot bearing and others the thowout bearing but I really dont know. I will appreciate any help.

does it sound like a whining noise? if so, its probably your throwout bearing.

pilot bearing on a nissan is good for 200k miles. it sounds like throw out bearing is going bad, lack of lubrication. try removing the clutch fork cover and spraying some penetration oil on the bearing.

Thans for your help guys. I will be working on it this weekend. Do you think I have to change the throw out bearing or just lubricate it.

Anyone know what other car use the same throwout bearing?
