Does anyone know if these bolts are aluminum?
I also had a clunking from the rear end and found my two smaller diff bolts loose, not enough to move them by hand, but not torqued to spec. If the bolts are aluminum, that could certainly be an issue (as far as breakage) if the proper torque is not used.
