So I was out killing some grass tonight when all of a sudden, I lost steering. Turns out, I had the main ball joint fail on me (where the steering box connects to the front axle). My question is; I've read in various places there is an upgrade you can do to the ball joints on these Cub's to improve steering and longevity. So my question is this; am I best off ordering a couple new stock ball joints or is there something superior I can get at my local Napa or O'Reilly's that is preferred over stock? Thanks guys!
