Churping Noise?

[Esther]

Hi All,
May be you can help me figure this out; I have a 1986 fj60. There is a very quite churping noise coming from what sounds like under the dash when the truck is in neutral and ideling. When I push the clutch in just a tiny bit, the noise stops. The noise is constant when ideling and sounds like a tiny churping bird. I pretty sure Tweety is now under there so what do you think it might be?

noise.

Maybe your tranny mount, but doubt it. I would guess a bearing. It could also be other things... When I first got my 60, the exhaust rubbed somewhere and squeaked, but stopped when I pushed the clutch in, so you might check around to see if anything is moving while someone engages and disengages the clutch.

My money is on the Throw-out Bearing being the culprit.

I would guess the chirping is from the throwout bearing going bad. Other possibility is the pilot bearing. But pressing on the clutch pedal and having the sound stop is classic throwout bearing.

I agree with the throw out bearing

There seems to be a debate about the throw out bearing noise. Some say the noise goes away when the clutch pedal is pushed down (This is the case with mine), others say it goes away when the clutch pedal is released. Anyone really know?

 

[FJ60Cam]

I agree on the throughout

Mine stopped making the noise when I pushed the pedal. It sounded like squirrels, though, so you might have a different problem...

You'll have to put in a 5spd to fix it

my 40s throw out bearing used to chirp only with the clutch out, but after about a week now it chirps reguardless of clutch positon.

anyone know what a new t-o bearing costs?

Throw out bearing!

Every one who I know that owns a older cruiser has that problem! Terrible job to do.

The bearing doesn't cost much, but there's a good bit of labor to get to it.

Then when you do get to it, you have access to alot of other things that are easy to fix while you're in there.

OK, if it is the trow out bearing I will replace it. I'll also do the piolet bearing, grind the clutchplate, replace the rear main seal, oil pan gasket. Anything else to replace once I have this thing down?
Also, before I tear into this job, someone in another link mentioned checking a linkage arm or rod that can be adjusted. Can someone direct me to what he was referring to?

 

[Landpimp]

its the throw out bearing, but unless its really screaming(or gets worse), I'd just leave it alone.

 

[Blue77FJ40]

You have to pull the tranny/transfer case to replace the throwout bearing. When you do, because of the amount of labor involved, you might as well replace the:
• pilot bearing
• throwout bearing
• rear main seal
• clutch
• resurface the flywheel if it needs it
• front tranny seal and gasket if leaking

i think the rod they are referring to is the master cylinder push rod which can be adjusted. it may make the throw out bearing quit squeeking but while the clutch is depressed but as you push the clutch in it should still squeek. at least in my case that's what happened, but it quit squeeking all the time and its an easy adjustment so give it a shot

 

[davegonz]

Dude..mine just started squeaking like yours. I barely touch the clutch and the sound disappears. I'm going to adjust the slave rod to see if it eliminates the noise.....and hope it's not the throw out.

 

[Esther]

Ok I like the sound of adjusting a the master cylinder rod first. Here is the stupid question... Where is the master cylinder? I know there is one on the firewall where the break lines go into, but I always thought that was for the breaks only. Is there another one tucked somewhere for the transmission? I assume the "rod" would be easy to spot once I spot the master cylinder.

 

[FJ60Cam]

It is attached to the clutch pedal. Pull the clip & pin and you can pull it loose. Adjust until you have little/no slack in the pedal.
