Accel/Rough Road Knocking in Rear
So I've been working on tracking down a horrendous noise coming from underneath my 05 4.7. It was originally difficult to explain because it was random but it's become more frequent.
The noise is coming from the rear end of the vehicle and is a very distinct knocking sound. It occurs whenever I accelerate at low speeds, it does it ONE time within the first 0-10mph and then doesn't do it again except when going over rough road, regardless of acceleration. It got significantly worse after I put my OME lift on last week? Anybody ever have a similar issue or any idea what could be causing mine? I could probably get a video/sound file if anyone is interested.
