ZF-5 Speed Grinding and Clutch not Disengaging

I just bought a 1997 F250 HD 7.3 2WD with 270K...It runs great, has good power, etc. There are 2 problems that I noticed when driving it home. The clutch was not disengaging completely, I would push it in as far as I possibly could and I could tell that it wasn't fully disengaged. After doing a few searches on here I read about the Clutch rod ends...which could be the problem. There is a lot of play in the clutch pedal before it starts to disengage I would guess half of the movement is play in the pedal, So I'm guessing that both the rod end and the pedal pin are both work causing the play. I'll be checking that out tomorrow in the daylight, where is the rod end located?

My other problem is that it grinds in just about every gear. The clutch only has 35K on it. I think the tranny is original. I'm guessing the synchro's are long gone. But the clutch not fully disengaging could be part of it too. It's not that big of a deal to me driving it with the gears grinding but the clutch pedal thing is bothering me. I've just been shifting it slow and easing it into gear which helps a lot.

(Sorry for the long post just trying to explain everything thoroughly.)

Check the rod but also check the clutch pedal bushing as they can wear out and become sloppy.

As far as the trans, ya your syncs are probably torn up.

You may have air in the hydrulic line. there Is a little bleeder valve on the slave cylender.... Just bleed it like your bleeding brakes.

Also new synchros is what should fix the problem with the grinding. But as long as you shift it slow, it will last a long long time like that.

I did also think about air in the hydraulic line as part of the problem too. I'll check my pedal rod and bushing tomorrow and give you guys an update. Thanks for the help guys!

jethro- I see that you and a couple others are close too. I bought the truck in Irwin, PA today...Paid $2600 for it and I think I did real good. It's a florida truck so the body is great. I'll put up some pics soon. Oh and how do you like that chip?...I have the same one.
