What kind of brackets, bolts, or bushings are utilized to fasten the air bag or spring to the axle and vehicle frame?

Spring mounts are the brackets, bolts, shackles, and bushings that secure springs or air bags (for an air ride suspension) to the car frame. Throughout your check, make sure the spring mounts are firmly attached to the frame and axles of the vehicle. Check to see if any bushings are broken or missing. Verify that none of the U-bolts or bolts are broken, loosened, or missing.
