my truck has all of a sudden gained a lot of free play approx. 2", theres no visible leaks, if any one has any ideas or any ways to diagnose this problem or has ever in countered this problem the help is appreciated. thanks

 

Replace the hyd clutch assy. Buy the complete kit from dealer or Southbend makes a kit also. The individual parts are almost impossible to bleed.
