Took 5 hours to replace
Replaced on 2002 Astro van. Original ball joints were still installed in vehicle. Had to air chisel and drive out original rivets. Rivets would not come out and had to drill them part way out then drive out with pointed air chisel. Would not recommend doing this in back yard if original joints are still installed. Have done many ball joints on several vehicles in the past. Did this at my friends garage with all tools and lift. Still took over 2 hours per side to complete.
Bottom Line Yes, I would recommend to a friend
