The fronts are a PITA, from trying (and failing) it myself and from reading a number of posts on the subject. I've held off doing my own for the time being, given that you have to drop the front frame to get the old ones out and the new ones in (something I think I'm going to let my mechanic tackle). Some have posted that you can do it without backing the frame down, but I simply don't see how. It's a matter of clearance.
