There has been a wheel bearing rumble that wasn't apparent the first time I had the front wheels up, but the driver's U-joint was obviously bad. So I pulled this side apart, hoping to find both, but these wheel bearings were fine. This U-joint will be replaced with a
sealed Spicer Life 5-1350X (same as all others except the front d'shaft which takes
5-7438X). The wheel seal for this 4600# D50IFS is a
National 415960, same as
MotorCraft BRS-16 &
SKF 27467.
