ZF-5 issue gets even better
long story kinda short.
i replaced slave cylinder and it worked out good except i couldnt bleed it. i tried everything.
so i said %#<¥ it!
i went out and got a full pre-bleed system. (works perfect)
now my new problem is caused by my old problem.
since i couldnt get it to bleed....i had to start my truck in first gear multiple times (100's) in order to drive it.
now im hearing slight grinding/squealing sound when put into gear.
truck does have a SB clutch with 30K on it.
any ideas? ty

I put a prebled system in and didn't have any problems. I ended up having to start mine once without using clutch right after my old system blew out. Dropped new system in with no trouble.
Was your tranny shifting fine before the 100 times you started it without master slave cylinder? Did it make any noise at all before you started having problems with old slave?

it did not have any issues before my slave went out.
im going to drive it for a few days and see if the noise goes away.
my thinking its NOT the clutch since it only has 20-30k on it.

Does the truck try to roll forward a little bit when you're putting it into gear without touching the brakes and you're on a flat surface?
I've started my truck while in gear plenty of times and it never has caused a problem. I've probably done it 50+ times.

And yeah, it would explain the noise, if it's literally making the noise as you push the shifter into first. What it's doing is starting engage the driveline as you shift, since the clutch is still not fully disengaging.
Do the fork travel measurement as mentioned above. Although I think you need closer to 12-13mm (1/2"-ish) minimum. If it's less, than look at the pedal / pushrod bushings. If it's at least that, then the fork and/or pressure plate are suspect (but at 30k, pressure plate should be good). Did you replace the fork when you did the clutch? IIRC, Ford has a new improved fork design, and one of the few OEM parts that don't, er, bend you over.

Agreed. If the truck tries to move at all with the clutch pushed ALL THE WAY in, you got a problem.
Pedal not having enough throw(floor mat of something under pedal)
Hydraulics not moving enough(air in system)
Fork bent(replace fork)
