My truck 02 Ram 1500 QC(5.9l, 4x4, 60,200 miles) has recently been shaking while I am braking. I don't feel it much in the wheel. I do feel it in the brake pedal more than the wheel. Rotors and pads were replaced about 15k miles ago.
I also heard a "thud, thud, thud" sound coming from what I think is the front passenger wheel area. The thuds become faster as I go faster.
Check the wheel bearing. Jack up the truck and see if there's any play in the tire. Since you just replaced the brakes 15k miles ago, I would start there. Then also look and make sure the brakes were installed properly and everything is secure. But I would be leaning towards the bearing.
The only reason I thought bearings is the thud. The op said the thud becomes more prominent as he goes faster, which I'm taking as he's not braking while accelerating. Maybe a combination of both?
