One Minute Good, next, not so much. Bent Fork?

2001 ZF6 with 83000 on it - only has a hypertech (I know, I know) but other than that, is stock.

truck shifted great coming home from work - but an hour later, fired it up, shifted into first and just didn't feel right - thought it must be in my head so I made a note of it.

Came to first stop, very spongy feel to clutch, but it went into first, I slipped it and off I went to the next stop - clutch in, shifter in first, brake on - engine lugging a bit - light turns green, I let off the brake, and the truck starts creeping forward and the clutch will not come off the floor. I pull it out of gear, and basically let it go down-hill to the house, where I had to urn it off, put it in gear, then use the starter to get it into the driveway - the clutch will still not come off the floor, and I have to yank it out of gear if under load.

I suspect 1 of three things (or maybe 2 or all 3, who know yet) and want your thoughts.

1) Bent clutch fork - would explain all the symptoms - and probably not dependent on mileage, but in truth, the age of my truck my be a bigger problem.

2) Master/Slave cylinders - no signs of leakage though, and seem to be working - I suspect these are still good.

3) Clutch itself is broken - or some other internal part like the throwout bearing or pressure plate.

Okay masters of the heavy metal - place your votes and rationalize them.

with 83k, i'd just replace the master/slave assy with a pre-bled system..(on my 3rd one, 170k.

Remove the slave and measure the distance from it, to the outer hole of the tranny. If more than i think 2-3/4in, its bent...

I think that it will be done if you would be spend at least 50k and make the nice solution to replace the master assy with the pre bled system.
