I'm new here and not real savvy with where to post this. I have a 2007 F150 Supercrew XLT 2wd 5.4L that has a mean shake in the bed at 57-60 mph. The best way to describe it is the bed looks like it's twerking literally! Tried different wheels and tires No fix, new tires no fix, new drive shaft, knuckle, slip yoke and U joints and no fix. New shocks nothing! I have done the spark plugs and coils. My truck has 93,xxx miles with a leveling kit and 276/65r18 and a Magnaflow 3" single in-single out. Only thing I haven't done was rear brakes but there not hanging up and I noticed there is some play in three of the rubber isolators for the exhaust hangers. Any help would be much appreciated!!

You might be better served to post a new thread in the section for your year model truck.

 

Ok thank you, I'm trying to figure out navigating this forum.
