I am trying to install a CCM 2.5 front and 1.5 rear leveling kit. I got the front installed with no problems. But the rear i believe is autoride. I take the bottom shock bolts out and lower the rear axle with a jack, but it doesn't lower enough to get the springs out? I have it lifted up high enough for room, but something is holding it from dropping far enough to get the springs out. Any ideas?
