When the rear of the car goes over certain potholes I hear something is loose on the passenger side. I hear a bang/rattle. Originally I thought my shocks were too short. A friend checked for me and said that is not the case. Unfortunatally, due to his heart condition he can't turn wrenches any more. I only checked the bolts on the front of the leaf.They were tight. We also recently removed the traction bars and I am positive my other buddy tightened all of the bolts from the u clamps. Do all of the bolts need to be tightened with an air ratchet? Does the car need to be in the air? Is there a diagram with all of the bolts listed so I can double check them? Any ideas. Thanks. Brian.
