lower ball joint
#4
There are a ton of DIY threads here on the forum that will guide you through it. The half shaft must be seperated from the hub assembly in order to get the old joint out and the new one in. Easiest way to do that is remove the hub assembly. Then seperate the lower ball joint and outer tie rod end from the knuckle and move the knuckle and half shaft out of the way. I usually go one more step and seperate the upper ball joint and take the entire knuckle off, it gives you way more room.
