Title: clutch noise
Post by: CJJay on September 23, 2012, 01:05:06 AM

I have 200 miles on the cj3a and started getting a noise from the clutch. the noise stops if I put it in neutral and let out the clutch. It doesn't do it all the time. Is this an adjustment issue. all parts are brand new.

A guess   throw out bearing bad.

Does it make a screeching noise when you press the pedal to the floor?   TO bearing..

Does it make the noise only when you are slipping the clutch to start off?  Pressure plate or disc..

If it is random and load dependent  you may be looking at gearbox bearings , not the clutch.

How is your adjustment? Is there adequate free play?

Was the bearing replaced when you didi th eclutch wiht a quality part?

Is your pilot bushing/bearing good and was it greased upon installation of the tranny?

I'm betting it's your throwout bearing, but it will not hurt to go through FBILL's list to track it down for sure. Mine first one had a little over a hundred miles on it before it started making noise. The one I have now has around 500 miles and it does it every now and then, but I've learned to live with it and minimize it. Unfortunately, from my experience and from what I've read, a lot of the aftermarket throw out bearings offered by a lot of the parts places are of fairly poor quality and it's more or less a craps shoot when you buy one. That said, making sure your clutch is propperly adjusted and that the throw out bearing is not spinning while your driving, will make them last much longer.

There is an inspection cover on the top of the bell housing that you can get to by removing the transmission cover on the body.

It is also sometimes possible to use a needle attachment on a grease gun to lube the bearings before installation, as the failure is most likely due to a lack of lubrication. It would take a fantastic controtionist to lube it successfully in place unless it is equipped with a grease fititing, which may or may not be connected with the hub it sits on and may or may not actually lube the turning bearing.

If the throw out bearing is not squealing when you lightly push the clutch pedal down to take up the free travel then your pilot bearing may be the trouble.

Does it squeal when in gear and the clutch pushed in with the engine running?
