There are many possible causes of noises coming from the area of the rear wheel, some are mentioned above , and no doubt you will get many more , because without more data it is a mite difficult to diagnose.
If you have wire wheels , make sure the securing nut is REALLY tight. of not the wheel can fret on the threads.
Is is possible (but unlikely without some poor maintenance) that the woodruff key in the half shaft can wear and allow some movement between the hub and the shaft.
There could be a wheel cylinder sticking on , which is allowing the shoe to rub slightly on the drum.
Is the handbrake releasing fully, if not the same symptoms as above.
Has the rear spring run "dry" and needs some chain lube between the leaves.
Are the axle U bolts tight? If not the axle can move very slightly.
Are the rear shock absorber bolts too tight and not allowing the rubber bushes to flex.
