I own a 2003 Ford F-150 fx4 with an off road package. I have rarely taken this vehicle off road. Leaf springs bands were moving off of leaf springs. They were replaced once, the bands continued to move, I was told that this was normal and there was no need for concern. At this time my vehicle was still under warranty. The last time I took in for repair the leaf springs were broken, because the bands holding them together had come off completely. I was told that this was no longer a warranty item and that I would be charged for repair. I feel that there should have been a recall on this item, my leaf springs were replaced twice because of faulty manufacturing. The pin holding the leaf springs together were made of plastic.
While driving 45 mph vehicle vibrated. Vibration increased radically at 55 to 70 mph. Vehicle was serviced, and technician determined rear end was too light.
