Hi guys, I'm in a project replacing front steering knuckles ( extremely rusted)...Also will be replacing u-joints wheel bearing hubs and bolts....The ball joints seem to be original 2011but have no play in them, the uppers will rotate but no movement in them....Should I replace or leave them in ????
