I wonder if the wheel bearing is bad or if something is worn or broken in the suspension.


Check the wheel movement, jack up the car and see if the wheel can be moved IN and OUT by pressing on the tyre RIM I had this and had about 1/4 inch IN/OUT movement by pushing on the edge of the tyre, It was probably the bearing HOUSING so I used LOCKTITE bearing retainer, and the wheel was stable ( next day) apparently that small movement could cause the shoes to grab when turning right ( this was on the left rear wheel)
