It is pretty easy, you just take the hub and rotor assembly off, drive the stud out from the front and then drive the new one in from behind.
*to get the hub and rotor assembly off you have to take your hub (or drive flange) off, the caliper (you can leave it connected to the brakeline) and then the bearing retaining nuts. It will slide off after that.
