You will need a couple of sharp "Sawz-all" blades to cut the shock struts off. The last time I changed a set of rear shocks on a C900, the shocks needed to be cut off because the upper nuts were rust welded to the "bolt" on top of the shock. Any penetrant oil will do for the lower bolts. While WD-40 is not my first choice, it's likely not the worst out there. Living in the great cultural vacuum of the mid-west, I usually use "PB-Super Blaster", mostly because the local Saab indy and nearly all the local pro's use it. It's a naphtha based product that has likely helped more than hurt me so far. When cutting the shock strut off be careful not to heat the shock absorber up too much or the high pressure in the shock will escape violently. After much thought and consternation I ended up using Boge shocks and like them well enough to say they don't suck. Good Luck, dave
