For few more bucks, get the whole wishbone from napa and there are no issues with ball joint or installation. The ball joint could be pretty stuck in the Diff case, I had a very hard time taking it out (salt + cleveland reasons) and ended up butchering the ball joint and cutting the ball joint bc I lost my patience. If you wanna go crazy offroading like tj and Tom, then I'd spend the money and get a 4 link.
