I changed all the bearings in my transmission last year to new ones. Nothing was wrong with them, I wanted to change them all out because I was taking the transmission apart anyways. After about 6 months, the ISB is making noise especially when the engine is cold and starting up. The noise goes away sometimes when the engine is fully warmed but not always. I know it's the ISB and not any other bearing because it squeaks when the clutch is engaged (pedal up) and goes away completely when clutch is disengaged (pedal down). Why do you guys think this is happening?
 
Agree with Ryan, sounds like release bearing, isb won't usually squeak.
Does it squeak with pedal slightly pushed?

It can't be release bearing. A bad release bearing squeaks when pedal is down and doesn't squeak when pedal is up. ISB is exact opposite (squeak pedal up, no squeak pedal down) which is what I believe I have.
 
Quite common to get a squeeky release bearing with the pedal up I've had it a few times on Egs and itr's

That's not true.
Try pushing on the clutch fork by hand and see what happens
 
Clutch fork mines doing the same thing wasn't enough grease applied to it when refitting anyone any suggestions on how to solve the squeak without taking the box out again
