Subaru Legacy lower Ball joint Removal and Install

recently i had to perform a brake job on my 1999 subaru legacy station wagon. i noticed a popping noise in the front driver side when turning left. so i started checking n i found the lower ball joint was pretty much destroyed. the local part store had one for 23.99. reading online i found the easiest way to remove and install the lower ball joint, get a mini 5 pound sledge hammer, a 14mm to 19mm sockets and wrenches, one you have removed the steering knuckle/hub smack the lower control arm. until the ball joint drops out of the knuckle assembly. it took me about 45 mins to remove n 30 to reinstall.
