Question

Answer
Ken,

The throwout bearing is going out on your truck.  Unfortunately, it requires the removal of the transmission to get to it.  It costs about $50 bucks for a new one.  But, labor is going to be the high cost factor.  For me I would do the clutch, pressure plate and throwout bearing at the same time along with a new pilot bushing/bearing.  If you can live with the noise it will last quite a while like this.  I say this because it is intermittent.  And, what is happening is after it gets warm the noise goes away so it has just started to fail...
