About a week ago I noticed that my left rear lift block had come off of the spring perch and slid back about a half inch. I loosened the u-bolts and hit it with a hammer and got it to where it looked like it was back on the perch and tightedned the bolts up. Today I noticed its back off and probly hanging off the perch about an inch. Im worried that it will squeeze out; since it is wedged shaped it seems possible for it to. I guess the center pin on the springs are keeping it where it is now. The blocks are a little over a year old. Soon ill be swapping them out for a shackle reversal but I need them for a little longer until I get the money. Im going to drop the axle enough to see if the little notch on the bottom that fits in the hole in the perch might be broken off, or if it just slid out of the hole and I didnt get it back on last time. Has anyone else had this problem before? Also, has anyone broken a lift block before? Ive heard theyll break easy but ive never actually seen it happen.
