How difficult is ball-joint replacement on this car? Is it something a general services garage could handle? Is it a do it yourself job with normal hand tools or are specialty tools needed? What else should be replaced while all is apart? The steering has been starting to feel "funny", pulls a little to one side, then i9t'll pull to the other afet a sharp turn in that direction. The caster effect also seems to be weakening somewhat. Does this suspension have upper and lower ball-joints? From what I'm saying here it does seem like it could well be the front-end getting tired. 185K and the upper control arms look new but I don't know about the rest.
Thanks.
