Mine started to do it after I had it for awhile. I don't remember, maybe a couple of years ago. It's not getting worse but it's something you just have to remember when getting on and off while running the backhoe or whatever. It likes to creep more in forward than in reverse, actually reverse is about normal. Anyhow, I have lubed the piss out of it with sprays and even white lube to no avail.
