Rear suspension on 1996 Ford Explorer

There is a "shock absorber" on the passenger side rear bracketed to the frame and the lower control arm. The thing is rotten with rust and needs replacement but I can't find it at the dlr or local parts store. Can I remove it or is there a suitable replacement shock absorber match? What is it called?
