how can you tell when the pilot bearing is going out? My Jeep has a roaring nose, sounds like gears are still turning and trying to catch up when I'm gearing down and then catches and is ok. It is not an all the time thing. It is a 4x4. I have disconnected the 4 wheel drive because I need to replace the sensor thinking this was it. I was afraid the 4 wheel drive was trying to kick in even through I did not have it in 4 wheel drive. I haven't checked the transfer case fluid or the transmission gear oil but I don't have any leaks around the transmission especially. I don't have any problems in changing gears, so I'm not sure if it is the throw out bearing also???? any help is appreciated.

More than likely its the throwout bearing as they get dry or they are adjusted too tight (should be about a 11/2" of frreeplay when pedal is up) they will howl and wear a groove into the pressure plate so usually the complete clutch assembly should be changed including the throw out bearing
