Driving home in Washington Beltway traffic the other day I noticed an alarming reoccurring issue that I thought was just a one time thing. I was in the middle of a torrential downpour courtesy of the latest hurricane or tropical storm or whatever that was hitting my area at the time, and decided to go into 4WD unlocked for some extra traction in the rain, to help me change lanes quicker and for extra grip around turns/ramps. What I noticed was a huge, and I mean huge, thud coming from the front of my truck after accelerating from 1st or 2nd gear. I would apply throttle, transmission would either already be in 1st or kick down to 1st without any hooplah, but then after releasing the go pedal, the truck would make a huge thud which would shake the entire truck as if I had just gone over a large pothole. Any ideas on what could be causing this?
