Hi
Here is something for you all to think about.
I have changed a total of 9 sets of wheel bearings in the last 2 months.
I have replaced 3 complete sets of bearings inner and outer. 1 set on a very heavy trailer the inner race diameter was 4 inches and 2 sets inner and outer on the front wheels of an f250 4X4.
The trailer the wheel and hub had departed the trailer, on the f250 the only reason the wheels and hubs had not departed the truck was because the disk brake calipers prevented this.
Theses bearings were badly damaged the cages were destroyed and rollers turned sideway etc.
The amazing thing I found was all three were full of grease there was not any sign of heat like you get when a bearing is run dry. I was unable to determine why they failed.
These three are the only ones that had grease in them the rest were dry and it was obvious why they failed.

Are you talking four wheel drive or two wheel drive on the F250 ? My ford super duty had a sealed bearing setup, they are not a greaseable item. Had one go out, and you would know long before anything was going to come apart . No mistaking when one goes.
