I got a 99 F550 crew cab with 18 ft flat bed tow truck and wheel lift.. The thing seems to be a dog and wont move out of its own way but thats totally different from what Im really worried about. Its got 166k miles on it.. Anyone have issues with the clutches or throw out bearings in these.. Had a new clutch put in it like 2 weeks ago after the throw out bearing exploded so like 2 days ago was driving it to go get a car and i noticed it was get worse and worse by the second.. All of the sudden it was like if I left it in gear and put my foot on the clutch the truck was still moving forward. Then it got to the point where I wasn't able to push the clutch in far enough for me to put it in gear then it got to the point I wasn't even able to start it... I ended up changing the master cylinder and slave for the clutch thinking do those first.. But it didn't make it any better after I did that I was able to push on the clutch and it was really soft then about half way down it got really insane hard where I couldn't even with all my might push it to the floor its like the fork is stuck or wedged.. Any one have problems.. Im about to swap in a auto into this thing..
