if your doing it, do both and the whiteline sway. The amount of work thats involved, trust me. Knock all of them out at once. Its good 12 hours if don't have a lift. Personally, I'd pay the dealer 500bux and let them do it.
I have it installed in my car and it was not difficult to install. It fits easy but as Barney said it was a lot of time but if you are a mech. I dont think that you will be more than 2-3 hours.
