I have a FX4 Ford F-150, 5.3 liter Triton. To start with I have always (as well as I can recall) had to wait for a couple of seconds after putting it into reverse, for it to catch before I can backup. This has never been an issue for me. However, approximately a month ago, I began to notice a banging/knocking sound. That occurred periodically. Additionally, When I first noticed that something was wrong, it felt just like I was getting a flat tire (in the front) steering and sound-wise. And hitting the brakes seemed to stop the knocking sound. But as this problem has progressed. When I apply the brakes to stop the symptoms, it begins all over again as I re-apply the gas. I am not sure if this is relative but it seems to happen more frequently when I have the A/C on. I pulled into my driveway a few days ago and now I am stuck in my drive. I start it and shift into reverse. But it only rolls back a little bit. And then my front wheels jump, jerk and hesitate making a terrible sound. I suppose that I could floor the gas and force it to go on back, but I am afraid that I will just break something else. This is my only means of transportation, therefore I am quite desperate to find a diagnosis/solution. I have spoken to my usual/local mechanic shop but unfortunately they told me that they do not have a clue. Any help or advice at all is very much appreciated. Thank you for your time. Cindy R.
