Well I havent gotten around to doing the guide rod mount yet, but I did change out my bottom ball joints this weekend. What a PITA that was. I changed the brake discs and pads at the same time, and even that was a nightmare. There just didnt seem to be enough room between the new pads for the new disc to fit in between!
It gave me the change to soak the subframe nuts with penetrating fluid though. Gave them many squirts throughout the day.
