Problem with brakes

Okay, so I replaced the front pads and rotors on my 2008 Tacoma 4 door 4x4. After that the steering wheel shake went away. I was still getting a shake from the rear end when braking, so I replaced the rear drums and shoes. The shake went away and now when I hit the brakes hard, the rear brakes kind of shutter. Also, while decelerating there is a vibration in the drive train.

Ive taken off the drums three times and reinspected and readjusted them. There not too tight and all the brake hardware looks good. I bought the drums and shoes from Auto Zone. I also replaced all four tires.

I inspected the u joints, they seem to be fine. But I noticed there is about a 1/4 inch side to side and up and down play in the hanger bearing. Can some please give me some insight.
