Clutch "Moan" and not in the good way...

I have had a strange sound in the passenger compartment when I shift, on and off for the last 4 months, I don't remember if it was present when I first bought it but I can't be sure.

Its when I am coming into the friction zone after having the clutch engaged (so easing the clutch pedal out). It will moan/groan loudly in the cabin during that period, the only time it doesn't seem to do it is when I'm easing the clutch out at very low (1000-1500) RPM. To describe the sound its almost a mmmaaaaaaammmmppp then I'm off and running.

It definitely corresponds to when I feel like I've made a sub-par shift, and I thought it was worse when cold, but now I'm not sure. I haven't tried the "Car Talk" "clutch diagnostic" test of finding a big tree and putting it in fifth to see if it doesn't stall immediately.

I originally thought it was the MC or hydraulics, since I had a slow MC leak into the cabin when I bought it, but I replaced the MC and SC and its still there.

Does this sound familiar to anyone?

I got a similiar problem, sounds like the TO bearing.

Pardon my ignorance but what exactly is a TO bearing, and what was your repair process? Does this seem to be the consensus?

I'm glad to have the input, as it has stumped a few people

TO=Throwout Bearing--the clutch fork presses on it--it is on the input shaft of your transmission, basically, and presses against your clutch pressure plate. When it presses on the pressure plate, it "disconnects" the clutch from the flywheel by reducing the friction caused by the pressure plate. Not an expensive part, but not an easy replace procedure.

Would the TO bearing cause more noise when I have the clutch fully depressed? Could it be a pilot bearing, as I've found a few accounts of others who replaced their TO bearing and still had the sound...

Should I put the t-case in neutral and try to recreate the sound by slipping the clutch to make sure it isn't somewhere else?

Does anyone know what exactly a dealer charges to do the job? I'm guessing at that point, I might as well get a clutch kit and have them do everything, anyone know how many "hours" this job would take the LR dealer?

Since u got it all apart, change it anyway, also check the mainshaft and its splines for any damage as well as endfloat. Also don't forget the new staple for the TO bearing, in fact order all of those parts, they're all cheap. Look at the condition of the fork parts as well.

Can't thank you all enough... It will just get markedly worse before it fails right?

And anyone know about labor costs?

I strongly recommend to change the clutch fork. They fail with time.
