noise coming from rear of. Rear end problem?

It could be many things, unfortunately and without hearing the noise first hand or being able to do some basic diagnostic tests or be able to drive the car, its hard to say what the source of the noise may be. I would guess with your car being front wheel drive that the backing plate is contacting the brake drum or the brakes are incorrectly assembled.

could be wheel bearing no rear end in that vehicle. is it a humming or is it a clunk or a clank.Under braking or always?

Did you have the drums turned when you replaced the rear shoes ? If not and there's a worn "channel" with grooving in it from the location of the shoes that you removed you would hear some noise from the new shoes being pressed into an old wear location. Also, did you turn the adjuster on the rear shoe assembly ? If you did not re-adjust the rear shoes properly after installing new shoes, you could also have problems there. I would remove the rear wheels, then the rear drums and inspect them to see if there is any indication of uneven wear on the new shoes yet (after first checking that there are no loose parts or other obvious issues). One other possibility...I had an aquaintance that replaced his rear brakes on his car. When he did the work, he reoved both rear wheels at the same time and "tossed" them aside. After the work was done he began noticing a humming/growling sound. It turned out to be that he had switched the location of the two rear tire/wheels and they were directional tires. He had both rear wheels rolling in the wrong direction going forward.
