Have a JD3033R. Joystick works fine to lift/lower loader bucket but suddenly started being floppy left/right and bucket won't curl. We're talking really loose and floppy. Looking for ideas on where to start. e.g. Is it more likely an issue with the joystick or could it be a problem with a hydraulic connection? Or something else? Bought new in 2018 and 500 hours. Used daily but mostly moving/loading manure and grooming arenas.
