It seems to be getting worse....
I have an 08 DC 4x4 base model, that has had the "shimmy at 10-15 mph (like axle hop) since new, but recently, it has a constant vibration at 20 mph regardless of gear. Perhaps it has always done this, but now I seem to drive more on residential streets at this pace per the speed limits, and it is driving me crazy. I think I have seen a TSB for driveline vibration but it was for lower speed. Does anyone else have this, and is there a fix?
