Duster rear end

Assuming you have car on jackstands, and assuming you can control the rear axle with a jack, I would loosen shackles but not remove, then remove shocks, then remove U bolts. Axle weight will be on springs. Relieve axle weight from springs, and you can see this as now axle should be free. Then carefully remove each shackle. If you have spare blocking or concrete blocks, "loosely" support under springs will prevent bad surprises
