i decided for now to just fix my ball joints and save my money and lower my truck later on. i was reading something about the upper ones having to replace the whole arm and not just the ball joint b/c they are pressed in. is this correct? would i have to get new arms for my truck? its a 98 ranger xlt. i have never done ball joints before but im sure i could do it. anyone have a walkthrough or anything that i can look at or should i just buy a book that shows how to do everything? all i really need to know is if i just buy the ball joints without the arm would i be able to get the old ones out and put the new ones in w/o having them pressed or whatever.
