Clicking noise in the rear

I recently am having a clicking noise in the rear of my alltrac. Only happens when taking a turn then taking off or when flooring it and stops at third gear and beyond. All this happens when the vehicle is on the ground. I put the car on the lift and no noise at all. I was thinking it might be a axle or differential part going bad. Has this happened to anyone before?

It's probably a crack rear diff mount, but that's more like a thug or clunk noise depending on how bad it is.

A clicking noise at rear can be due to worn parking brake shoes within the rear hubs. I replaced the shoes on my ST185 hubs and noise went away. Fixed.
