Since the driver's bearings were good, I pulled the passenger's hub off. By the time I got the brakes off, I could feel the roughness, but I didn't expect it to be as bad as the inset shows. Since I'm waiting for a U-joint on the driver's side, I swapped that good hub & bearings to this side so I can put one of them back together. The outer bearing (Timken LM104949 roller & LM104911 race) is
Timken Set 38, which is apparently also the rear outer bearing. The wheel seal for this 4600# D50IFS is a
National 415960, same as
MotorCraft BRS-16 &
SKF 27467.
