My front wheels have a little play when tug the tire in and out, so I'm assuming I need new bearings. I haven't changed bearings with seals before. Any advice / gotchas I should be aware of so I don't screw it up? This is a 63 Polara 500. - Jim Jim Altemose, Long Island, NY '63 Polara 500 (Max Wedge) '63 Polara 500 (383) '65 Belvedere I (Street Wedge) '71 Bronco
