It's also possible that the brake on that corner is grabbing for some reason. After a short drive stop and check (carefully) the brake and wheel temps by gingerly touching them. Compare side to side to determine if you've got a dragging caliper. You could also jack the corner in question up and see if the wheel rotates freely. A dragging brake can be caused by heavily corroded brake lines ( they will squeeze but not fully release), a broken pad surface or a seized caliper ( in this case a stuck piston). If it's dragging, you would PROBABLY notice a pull to that side occasionally. It's worth investigating as it could suddenly get worse and something could break.
