I've been reading about this procedure both on this forum and others and still have some questions.

1) I've read that's its possible to remove the dogbone without compressing the spring and without using a puller. At least one person claims that simply removing the nut that holds the guide rod to the LCA (the bolt is still trapped by the spring perch, of course) gives enough wiggle room to unscrew the dogbone. Anybody have any luck with this method?

2) I'm not sure I understand exactly what problem a puller/removing the above nut is supposed to solve. Is the dogbone simply too wide otherwise to unscrew without hitting the bottom of the car?
