    First thing I would check are the diff mounts/bushings. If you hit that hard it may have broken the mounts.

    Is the axle bent? I am assuming you put in a new wheel bearing along with the new hub?...I am also assuming that this noise was not present before you wrecked? If you get the chance I would raise the vehicle in the air and run the car and grab a mechanics stethoscope or screwdriver and try and pinpoint where exactly the noise is coming from...Also as mentioned I would check the diff mounts and also the strut/spring

    I would also take a look at the strut, I can say from personal experience that the noise my rear strut was making" a clunking type noise" had me thinking something was wrong with my diff until I figured out it was the strut by finally getting it to make the noise while not moving.
