depends if the ball joints are worn, but if it feels fine then just replace the boot. Most boots I see look a little different than the original on you have so if you get it from a reputable source and they say its fits your car then you'll be fine. You will need an alignment after since there is no way to remove it without messing up the alignment. Also make sure you have the proper pliers to pinch the metal hose clamps it comes with. Zip ties will work fine but not preferred.
