yo!One ball joint?
Also, will they do an alignment after? How is the tire wear?
It happens, start reading DIY articles here to save some $ on repairs that you can do at home; ball joints are tuff for some; but in time. you can do it.
At Auto Zone (don't like the quality of some of their mech./electr parts tho) and other places, you can rent or borrow w/refundable deposit some tools to DIY.
GL!
I gotta agree with Miesk. The cost of a set of ball-joint tools is maybe $75 (I got the Standard AND Master kits on sale together for $49 and they've worked fine. I've done 4 sets now) and once you buy them you have them forever. As long as you own a reasonable set of hand tools you'll spend *maybe* $75-$100 on the specialty tooling you need for ball-joints.

While I'm the first to admit that cheap tooling isn't always the best, if it's something that gets used maybe 3 or 4 times a year then sure, cheap is good enuf. Sure, I buy Snap-On wrenches but I don't buy bearing-separators and other limited-use tooling from them. Sometimes good-enuf is good-enuf, I don't feel that *every* tool in my chest has to be top-notch. I'm not so proud that I won't but Chinese tools

Generally speaking, the *first* time around you'll probably spend as much to buy the tooling and parts as you will to have the job done at a shop. BUT, after that you own the tools and you know how to do thee work so the only thing you're left paying for is the parts, and if you don't mind doing your own work AND have the tools at hand it's not such a big issue to buy the cheaper parts that need to be replaced every 3 years instead of every 5.
It should be a given that an alignment follows a ball-joint replacement (at least with any *reputable* shop) and as long as it's aligned afterwards there should be no tire wear issues (of course that assumes that you rotate the damn things)
Now certainly this is just my opinion and by now we ALL know that opinions are just like asses, some are nicer than others and I have no illusions as to where MINE stands in the rankings. Take it for what it's worth (the opinion, not the ass)
