Clutch problem. Clutch was replaced 3 yrs ago and within the last week its been getting harder to get in & out of gear. Since it is still fairly new I replaced the slave cylinder and now I can't get it to pump up. Ive bled the line many times to no avail. Could it be the Master cylinder? Any thoughts would be appreciated, Dave

 

Get under the hood, and get someone to sit in the truck and pump the clutch a few times, and just listen for any hissing, or gurgling noises, then you can see if the master cylinder is gone. Also, did you replace the lines? Check to see if there are any lines or fittings loose or leaking.

 

I did not replace the lines, however in doing as you suggested with someone else pumping there is a noticable sound coming from the master. I found no leaks
