I just got the first rear spring off tonight on the driver's side. I compared the old and new springs and everything lined up. When I went to mount the spring, I could align the pin on the spring pack with the hole in the bottom of the axle bracket and could put the rear shackle on. The front eye was so far forward that I couldn't get it lined up. I took the ubolts loose and can get both the front and rear of the spring mounted, but then the axle alignment pin is about 1/2 inch behind the hole it needs to go into. The rear shackle is also tilted forward instead of straight down like it was before.
What am I doing wrong? Do I need to have both rear wheels off the ground instead of just the one I am working on? As it is, I can't move the axle enough to make this work.
