Re: leaking rack
I recently bought and replaced the rack in my EL. The new rack cost $400 odd, including new tie rod ends, and it took about an hour. I don't know about the AU, but there are a few little tricks with the EL in order to get the rack off easily. I can tell you if you wish.
"D" rubbers on the sway bar: about $40 and 20 minutes. Get eurothane ones, they last longer and are more stable.
