Reason I ask is because i had a guy with cub cadet with the plastic front wheel bushings, they were wore all to heck and the spindle was sitting on the bottom of the bushing, instead of being supported all the way around, hard steering... There was minor wear on the spindle which surpised me as i was expecting it to be D shaped instead of O.. New bushings and he was good to go. Same as on my SRX75 rider a few weeks ago. front wheel bearings (ball bearings) were plumb wore out, hard steering, replaced them and it steers like a dream.
