Jd 7775 bucket creep

[RLServices]

My 1996 JD 7775 skid steer is having a weird bucket creeps down issue. It only occurs after a heavy load, say breaking into a snow pile, then it'll seep at a varying rate between occurrences. One time it'll creep fast, one time it'll creep slow. Sometimes if I bump the boom up, the bucket creep will stop. Today for the first time I also had the boom creep down, bump the bucket pedal, and the boom creep stops. Like it's haunted, as its really inconsistent. Maybe some gunk in the spools? Or a sticky pressure relief?

could it just be bad seals in the cylinders, and pending the amount of weight in the bucket and how HIGH the idle/rps's are (lower rpms, can cause less power to all things)
OR even how worn the coating on the cylinders are which can cause slight leak down, even with good seals in my experience any how
not enough to leak oil, but will cause bleed down and need to re adjust bucket curled back! or lift boom!

No, because lifting the boom with the same load in the bucket the odd time will completely stop the creep of the bucket. Same weight on the cylinders. Has to be something in the controls. I have cleaned out around all the pedal linkage

My thought was a sticky pedal, not quite returning to center. You say you cleaned out around the linkage but what about lubing or greaseing the pivot points on the pedals?

All moving freely, I have to push on the bucket pedal for up until I can hear the hydraulics start hissing for the bucket to stop moving.
