I have recently done work to my truck getting it ready for riding season. I have done front and rear brakes and rotors and calipers all brand new, brand new Turbo, ball joints, and an array of smaller more minor things. After doing this work to the truck I now have a mysterious vibration/rattle that happens every once in a while and it is driving me crazy. I suspect it is either the front cab mount bolts somehow or possibly my bed is loose and vibrating somewhere. Is there anywhere on these trucks that is a common place for vibrations to start at high mileage? My truck is a '06 with 235k on the body. The noise is not present when sitting idling and only shows up about every other time you take off from a stop. As soon as I go into the throttle it makes the noise then it either completely goes away immediately or it gets quieter for about 2-5 seconds then goes away. Am I just chasing something that doesn't matter or is there something this could be that should be fixed?
