$160 for swaybar bushes! WTF? You can get a complete larger swaybar kit for between $200-250.
Do the ball joint yourself, just pull out the spindle and take it to a suspension place to get the old one pressed out and new one put in. Cost me $30 to do this. Personally Id recommend getting both the top and bottom one replaced at the same, if they are original then chances are they both near death and saves you doing 6months down the track....
As for springs and shocks, depends on brand....
