My truck has started behaving oddly. At 50mph, not 49 and not 51, it will start to kinda buck and bounce a little. Like driving over a washboard or something. Drop a mile an hour, smooth ride, speed up, smooth ride. It seems to get progressively worse the longer i hold it. It's a bit more severe than annoying as 50 is about what I cruise at alot.
What could it be? Not RPM related as it doesn't do it in other gears held at the same rpm. seems harmonic in nature due to the exact speed and the fact it will get worse if you dont speed up or slow down.
i have some fabtech trac bars in the garage, haven't had the chance to put them on yet but I doubt that will do anything for it.
thanks for any things to check!
