GEN 2 Pinion Bearing Failure - New Part From Ford

[Muchmore]

Was the fluid ever changed? Worn out gear oil is the primary cause of differential bearing wear/damage.

Why would he have it changed before 72k?

Mine pooped out around the same time. Weird.

My 18 has this whine/hum now and going ASAP. About to see if this wrap warranty worth a phack!

I got lucky! Warranty replaced both front and rear differentials at 86k.

Because 72k miles on an unchanged lubricant is insane...?

Remember manufacturer’s suggested is under perfect conditions… and they mean perfect! Otherwise look at severe, which in the really real world equates to “average”.
