clutch problem or something worse?

Ok so I'm having clutch problems in my 2000 tj 4.0. I replaced my clutch and flywheel in march and everything else including my slave cylinder. The other day I was at the store when to put it in gear the pedal had less pressure than normal and when I tried shifting it wouldn't go into gear. And when I tried a little harder to get in reverse it lunged really bad. Had a friend tow me home pulled the slave off to make sure I had good pressure in the lines. Seemed ok gave it a few pumps and pressed the pedal and it worked fine.

Reinstalled it and it shifted fine but still didn't feel as stiff as it did before. Drove it maybe 10miles and it did it again this time at home. Talked to the guys at pepboys they said either air in the line or a bad slave so I went ahead and replaced the slave since I had the lifetime warranty in it drained the lines blew it out to make sure nothing was clogging it. Filled it up. Pumped the slave until no air came out put it in and still won't shift into gear and the pedal still isn't quite as stiff. And on top of the new slave where I should be able to bleed the air out it is sealed but still has the fitting for the set screw that goes there.

Anyone have any thoughts as to what is going on?

How about the master cylinder that drives the slave? It's obvious your not getting clutch disengagement.

ok so i have now changed out the master cylinder and still nothing. when i pull the slave off and pump it by hand i am getting good fluid flow from the master cylinder and no air bubbles, when i reinstalled the slave and pressed down on the pedal there is barley any fluid being sucked out of the master cylinder and it still wont go into gear

Sounds like air in the slave. All ya can do is pump it to try to get the air out.

got the tranny down today it looks like my throwout bearing is getting caught on the shaft right where it transitions to the teeth and not sliding back and letting the clutch disengage and it is causing some extremely uneven wear on the pressure plate where it makes contact

Check the fork mount on the opposite side of the bell housing, it could be a fork issue or ball or that retainer spring.

The retainer spring is fine I actually replaced that when I did my clutch and it still looks good and is holding the fork on. When I slid the fork out the rear side of the throwout bearing would catch and I had to jiggle it to get it to actually slide back. What would I need to check as far as the ball where the fork pivots
