So I put on my 35" bfg M/T's on hummer wheels friday, shortly after that my clutch pedal got stuck in the "up" position, couldnt put it down for nothing, after the 3rd or 4th try it went down, I pulled over to see if somthing was wrong but nothing looked out of the ordnary. Then today it happened again, nothing the first try, on the second it fell about half way and the 3rd try it was fine. The only mods done to the truck are a smarty (was at #5 now at 1) and the 35's. What could cause this... I dont think theres contanimation, the caps never been off. Its not low fluid cause theres plenty of pressure when it is normal. I checked if there was something in the cab causing the pedal to stick but no dice. Its clear in the engine bay too. Any thoughts?

Edit: 24k miles

 

Look under the dash and check all the linkage. Something could be blocking it.
No other idea`s at the moment.

 

Wonder if the clutch is slipping and overheating. That will cause the plates to stick to the flywheel.

plastic pin wears pretty bad on the linkage. my done the same thing about 3 days before it failed.

 

Thats seems pretty likely with the big tires and they heavy power off the smarty... Ill keep an eye on it though. I know its not the linkage ive looked that over a few times and right after the master cylinder leaves the cab it goes hydraulic, so its not external. I guess the good news is I get to crank the smarty up after my I get a new clutch. You guys got any suggestions, I really dont care about noise, or pedal effort, I want the most bad assed clutch that wont break my drivetrain.
