An insufficient weld may exist in the reinforcing gusset plate on front, right and/or left spring hanger, or the weld may be missing entirely. The spring-hangers are brackets located on either side of the axle. Defective or missing welds can cause cracks to form in the spring-hanger.
If the hanger is cracked, the gusset and the crack will be welded. A replacement hanger will then be ordered and installed as soon as possible, without charge to owner.
