"AS stated in a later post on ball joints." Changing out the ball joints should take a couple of hours per side, maybe longer depending on the experiance. There isn't any rivets to drill out though,they are on non 4x4 vehicals. I think that it is alot easier then changing them on a non 4x4. There is no spring pressure on the ball joints. If you have air tools then you are going to be happy.You'll also need a spindle socket, maybe a four prong one. After you put the ball joints on the spindle and connected to the axle housing and bolted down, grease the upper joint before you put the axle in. Because the grease fitting will hit knuckle on the axle. The ball joint should come with a plug to take place of the fitting after it is greased. The job isn,t all that hard. Hope I helped any.
