I love my old 1992 King Quad 300 but the rear axles need the u joints replaced. Any suggestions on a great place to buy the joints and what a part # would be. I've tried one is completely destroyed and the others have no grease left in them. I tried ordering from PowerSportsiD but their system is wrong and the joints are the wrong size. I don't want to buy oem parts and pay their prices. Any help would be apprecieted.
