You don;t need to pulla ny bolts on the arms either. Just unbolt the lower end of the quad and reg shock. then, get a long pipe (jack handle maybe) and pry one side of the reaend down. The spring will pretty much fall right out. I've done it nearly a dozen times.
I just removed both upper and lower iso's on mine. I did it by removing the bottom shock bolt and I didn't even have to pry down on the axle. I already have my quadshocks off, so that made it that much easier.
