If you live in a salt roads region then be prepared for frozen attaching bolts at the control arm bushing attachment areas. This can turn in to a nightmare if they are frozen. Have plenty of PB Blaster at the ready. When you do get them off you can also drill out the old rubber part of the bushings if you don't melt them out. PB Blaster the hole where the bushing is pressed in and when you get them out make sure you thoroughly clean the arm bushing hole and you can grease that area when you press the new bushings in the make easier. C-clamps and presses make it all easier like TigerEyz3 and Yukoncount said. Having a trusted shop do it is even easier. A good one will prep like I stated. Clean everything else like upper arm cams, all bolts, all nuts and mount areas. Lube the ball joints while in there and if they are old enough replace them while you are at it. New cotter pins.
