Is there a difference in circumference size on off name brand ball joints compared to Polaris stock. I replaced the lower ball joints on my 2013 Sportsman 850. The old ones had to be pressed out. The new one just went in with minimal hand force. The wheel assembly is very loose and the ball joint that enters the a arm hole actually moves in the hole. The ball joints were for this model. Has anybody run into this problem. I can’t imagine that the hole in the a arm got wider with riding. I am guessing that there is a problem with buying off name brands. Before I spend anymore on this, I want to locate the problem. All the bushings are tight.
