Question: rumbling front end at low speeds over uneven pavement

Over the last few months there is low, rumbling noise in my front end starting at low speeds ( 5 –20 mph ) and up-to about 35 –40 mph, especially noticeable over uneven pavement. The noise is not segregated to the left or right sides and to be quite honest there are days when I want to drive this car into a wall. Interestingly - the noise is not present when your foot is applied to the brake. Other than this annoyance, I love the car, it still looks great and after almost $4000 in the last few moths to attempt to solve the problem, I really can’t afford not to keep it. ANY ADVICE PLEASE!!!! Here are the components, replaced since January 2010:

suspension struts
frt right wheel hub
lower joint assembly/steering
stabilizer bars
control arms
break rotors, pads
new tires
sway bar links
shocks
shock mounts
rack and pinion
steering shaft assemble ( into rack and pinion)

Also, was hoping to see a diagram of this car’s suspension components in hopes of seeing something that perhaps has been missed. This car has been to 3 reputable certified BMW shops and a dealership in attempt to address the issue.

    I replaced all four wheel bearings on the same vehicle and now have a quiet smooth ride.
