Has anyone else suffered complete bearing failure on their 4X4Labs rear bumper swing out? Discovered my spare tire swing out was super loose after a trip. Eventually accessed the spindle with a lot of hammering and screw driver prying. Turns out the bearing rollers turned completely into sludge. Anyone know what bearings these are and how to remove them? It seems I have to remove the whole swing out arm, but I can't figure out how to remove it. The bottom bearing is still attached. Is it just a lot of upwards force required?
