I have already searched the forums looking for answers, but I figured it couldn't hurt to give some specifics and see what kind of responses I could get. My truck has 213K miles on it, is in overall pretty good shape, but it is 15 model years old with all those miles. This front end noise happens mostly at low speed when I first take off. It sounds like flexion really. It's a kind of groaning and a light "thunk" when I accelerate from a dead stop. Also, if I kind of lurch it in first gear, it does it when the front end lifts up and when it goes back down. Sometimes I hear it when I come to a complete stop as well. I experimented today and tried holding the brake down and easing the accelerator on and I didn't hear it. I was kind of trying to rule out drivetrain stuff I guess. At any rate, when holding the brake down and applying accelerator the noise isn't there, only when the body moves from accel/decal. The location of the noise seems to be from the front driver's side. Any input would be helpful, feel free to ask anything additional that you need to know.
