Thunking in the rear ?

[mazdaagain]

Getting a thunking noise when I drive in the rear right of the hatch. Had the back hatch full of stuff (lots of weight) and no thunking. Unloaded the cargo and it's back. Pretty sure it's something with the rear suspension.

Anyone know what it could be ?

Have your rear struts, mounts and swaybar end links inspected. They are the usual culprits. Could even be a loose strut.
