Hi. i needed replacement rear bearings and the brake backing plates. I got 2nd hand hubs with backing plates and all fitted. Replaced the bearings on the 2 replacement hubs and re-attached everything. However, when i tighten the hub nut onto the driveshaft, the more i tighten the nut, the more the hub grinds to where it wont actually spin at all. Its as if the abs ring is grinding on the inside edge. Does anyone have an idea what could be the problem?
