THUMP when stopping

[00Stroke7.3]

My 2000 7.3 has 149,000 on it. I'm pretty certain the front end hasn't been touched. It just started doing this about 500 miles ago. When I slow from cruise with medium pressure on the brake pedal just before I come to a stop I hear a thumping sound and you can feel something hitting through your foot on the floor board. Had a mechanic look at it, says it's definately suspension oriented but he couldn't find it. I through it up on the lift and couldn't find anything loose. Calipers are tight ball joints are good. I'm at a loss, I could spend some dough and just start replacing stuff but that would be a little counter intuitive.

At least I'm not alone in this.

There is a body mount there and as the brakes are pressed, you feel the truck "lean forward" or nose dive a little. More weight is being transfered to the front axle and is supported in part by these body mount bushings. In my case I could feel the thump on stopping and a light creaking in the floor on speeding up again. Try tightening up the mounting bolt under your feet, but the bushing may need replaced.

I AM SHURE THERE ARE MORE OF US. BUT ON THE GOOD SIDE THIS TRUCK HAS 110.000 MILES AND HAS BEEN MAKING THIS SOUND SINCE IT HAD 80.000. AND NOTHING HAS FELL OUT YET!!
