1992 f-150 super cab Ball Joints HELP!!!!!

I have a 1992 f-150 super cab and I need to replace the upper and lower ball joints in the front end. I know I should take it to a shop to do it but I would rather do it myself. Can anyone tell me how to do this??
Any help is greatly appreciated.

go to your local parts store, and ask for the special tool. Then just take off your wheel and brake assembly to get to it and replace them. Pretty straight foreward, just takes a while.
