hi, just look for some clarity.

After a road trip at xmas I noticed a sound coming from under the car like some distant army helicopters. The sound fades in and our and doesn't increase or decrease with a rev of the motor. If I push the clutch in, it goes away. Sometimes I can hear an audible spinning sound a bit like a worn bearing. instead of the chopper noise. Is this a through out bearing? Any thought appreciated.

Does the noise disappear when you select 4th gear?
As that is when the mainshaft is direct coupled with the output shaft and reduces the load on the layshaft bearings.

My R380 is about to be pulled out and rebuilt to get rid of the potential of another apocalypse now, with choppers!

If it was the throwout bearing, I would expect it to make a noise when the clutch pedal is depressed. That is when it is doing the work.

Cheers, Mick.

In general,

Clutch pedal in and noise heard = throw out bearing

Clutch pedal out and noise heard = Gearbox input shaft bearing

Pressure plate springs are known to rattle on PUMA's.

Without hearing the noise, it may be worth considering.

Only Landrover can come up with a part called 'Throw out' ...and expect it to work,

“Throw-Out bearing” or “Thrust-Race” is standard terminology for this part across all of makes of vehicles.

yes guys it is when the clutch pedal is pushed in.
Do they fail un-expectidely or just get noisier. I have another 5K before the next scheduled service

thanks for your knowledge

Not common for them to fail unexpectedly.....in that, if they have been subjected to lots of water, or foot resting on the clutch constantly, city vs country driving...it isnt unexpected:p.
