Today (Sunday) I attempted to swap the springs on my car. And I guess I would classify the result as a light failure. I got the front strut assembly off, but I couldn't disassemble it. I read that lowering springs shouldn't need to be compressed to be removed, but the fact that the top mount was not "already loose" as described on these instructions
was making me nervous. And it was getting late. So what makes this not a total failure is that I was able to get the strut back in the car properly.
So I figure, knowing how to remove and reinsert the strut is half the battle. Considering that I've never even used a socket wrench before, this whole thing was very educational even if it accomplished nothing. Once I find a place where I can borrow a spring compressor, I'll try it again.
