the boots actually aren't your leaks source. the boots are only there to keep dirt and other debris from the ram and seal area the boots are filling with fluid and it is dripping out so replacing the boot would do you no good. what is actually leaking is the seal that the rack slides through. this really isn't something an inexperienced person should tackle. removing the rack in it's self is quite a job. you have to partially dissasemble the front suspension in order to remove the front differential, which has to be removed so you can slide the rack out. it is quite involved. there are rebuilt racks available, so you may search for that and consider that an option.
