i've got an older turf tracer with lots of hours, hydros work perfect except for a little whine when cold. i changed the hydro oil and filter and while i was at it i checked the play on the wheel bearings and both sides seem to be a little loose. i figured they were like a wheel bearing on a car and i went to try to tighten them up and noticed they have quite a bit of torque on them so i left it the way it is for now. i cant find any info on this in a search. is a little play ok and i should just leave them alone?
