What's required to remove the rear spring?
 

I want to replace the height adjustment bolts since the rubber is shot and I want to adjust the ride height. I did the front. Moving the knuckle on the front is not too bad since there is no drive shaft.
I watched a video of someone pulling the rear spring and he disconnected the shock and sway bar link on one side and was able to get the spring out. Is that all it usually takes? I really don't want to take ball joints apart on the rear if I don't have to. I don't think I can get the bolt out of the end of the spring with it in the car.
Pulling the spring seems like the best option for this.
Other opinions? Link to good videos on doing this? All help is appreciated.

The attached procedure is what I just used to pull out the height adjuster. If you do one side at a time there is no need to pull the spring.

I have been soaking the bolts with PB for over a week now. I am still expecting to strip them if I try and spin the bolts with the spring in the car. At that point, I expect to take the spring out to be able to finish the job.
If the spring will come out without touching the control arms, I think that is the way to go.

Here's something you can try that's worked better than even PB Blaster for me. Background: I have worked on old woodworking machines in the past and it's not uncommon to find bolts that are rusted solid to the point you have to cut or break them off or so I thought. Over the years, someone told me about making a 50-50 mix of ATF and Acetone. Soak the fastener up with it, let it sit a while and most times it will work better than PB Blaster, WD40 and most of the other products I've tried over the years. I also like to use a low impact pneumatic wrench to try and break the fastener loose. I've used it and gotten a lot of fasteners broken loose I fully expected would break off and require drilling out.
If you want, try it and it may surprise you. Good luck.

Patience paid off in the end. One one side the collar broke free from the spring. A little heat on the bench and the collar broke free from the bolt. Epoxy the collar back in the spring and put the new bolt in. On the other side the sprayed PB blaster and tried with weak impact tool for awhile. Finally got the air impact out and it brock free. I guess the PB finally worked enough. Put the new bolt in. Now I have to actually go through the process of adjusting and checking to get the ride height where I want.
