I installed a 4inch RC lift about 3 months ago. All springs. However, today while changing my gear oil. I noticed that the 10* wedges in the back where missing.(the little thinks onthe bottom of the springs, about 5-6 inchs long.) The right side was gone completely and the left was craked through! What an i to do about with. There is about a 1/2 inch gap between the spring and the axle. I'm not sure how they broke or what to do about it?
