While You're There
While doing this installation it's an easy time to do other installations such as sway bars and endlinks. Maintenance items such as the Balljoints that can be on their way out, or potentially damaged while removing the stock arms are a good idea to have on hand, or replace at the same time as they make the whole procedure easier.
