You're going to want to inspect your ball joints real carefully and if there's any chance at all that they're original... replace 'em. They're time bombs and if you're lucky they squeak for a while before letting go. There's no captive safety on them, when they let go your car falls to the ground and your tire wrecks your fender and you have a super bad day.
Most people opt to buy whole control arms (with the ball joint built in) because they also come with new bushings and are fresh and rust-free.
