This is the cradle.. http://www.cadillacfaq.com/faq/answers/bushinginstall/index.html There are 4 big bolts that hold it in.. They are.....the cradle bolts.. This write up on the GC kit even circles them. http://www.cadillacfaq.com/faq/answers/gcinstall/index.html

I did not disconnect the sway bar to put the rear springs in. I'm fairly certain I didnt disconnect the front either.

I also didn't remove any control arm bolts when doing the rear springs.

I'm assuming that the more you jack up from under the lower control arm, the less the upper will snap upwards when you take the bolt out, right?

yes.

Yeah, lowering the cradle also helps drop the lower spring perch for clearance to pull the spring. I'm not 100% certain, but I'd imagine that if you drop the whole cradle for installing those bushings, then the springs would most likely come free. The cradle can be dropped one side at a time; that's how I did it. It's not too difficult to accidentally back the cradle bolts out all of the way. In fact that's what ended up happening when I did it. example: put the jack under the cradle on the passenger side and jack it up until it's just putting upward pressure on the cradle. Remove the bolts. slowly lower the jack/cradle until the spring was free. Swap in the new spring. Then jacked it back up into place, and used an impact gun to re-seat the cradle bolts. It's a LOT easier to reinstall them if you have an impact gun..

yeah, I didnt do endlinks on mine so I can't offer much help there.
