Well, what do you mean by play and where is the play ?? If you mean that when you jack that wheel off the ground and try to turn/spin it and it has some free-play,, then I think the wheel and maybe even the drum need to be removed and looked to see just where that play is.. If it turns out to be in the axle itself then some play is normal.. If its between the hub/drum and the axle then maybe the hub just needs correct tightening, the axle and/or hub replaced, or an axle/hub shim may work..
