So replace the ball joint too. Your can get all of the parts and have it done for a little more than you'll pay for the Dorman crap that's $50, and get a lot better quality. Remember, you get what you pay for; and there are only few exceptions to that rule. The reason it's so expensive to have it all done at a shop is labor (usually about $80 an hour, and they still use the cheap parts and mark them up to sell to you).
