EX eating hub bearings faster than I drive it. What could it be?

How are you pulling the bearing into the knuckle? If it's going in at a angle and distorting the housing it could be part of the problem. I usually pull them in a little at a time with the bolts, in a criss cross pattern like tightening a wheel. Also, make sure the mating surfaces are all clean and free of any rust scale causing a uneven surface.
Agreed here
Also it should not be needed BUT have you packed any additional grease in through the abs sensor hole?

Agreed mr Anderson from lube tech and myself have gone over this on other things but never sought out what was in an assembly like this to match it up. I bet I could ask timken seeing as we are about to purchase two $68k bearings for work. I'm willing to bet if I gave him the part number with the bearing in question he could find out what they are assembled with and a direct match could be had

Famous last words tell that to a family when a wheel comes off and kills the dad
Oh wait it happened here on a garbage truck
I done run dem lug nuts on wit da impact I figure dey were tight enuf, said the 20yr wrench that put the tires on the day before
Not properly torquing this might work in a shade tree shop and be called "good" but someone who actually takes pride will use a spec on key Componets. Will you bust out a torque wrench for a hood bolt no.
Case in point bolts on the car shredder at work used to be put on to what felt like tight enough and guess what they broke ALL the time
Then we got a hydraulic torque wrench and bam they stopped breaking all the time
And as a test we checked we were about 250lbs off the spec

That's because there are too many different people working there. Some things do need to be torqued, even by the pros including me.

Yeah, connecting rods, main bearings, head studs I don't know what those are, and I certainly would not use a torque wrench on them. Body-off restorations of Vettes, pickups, VW's (among others) I could go on but I don't feel the need to throw a resume out with my (alleged) years of experience.
What's that new cologne you are wearing?
Oh, smells like "Desperation."

Actually mr super 10 year shade tree I'm going on 12 years full time wrenching now moving on to over seeing maintenance diagnostic and repairs of 3 yards in which we have 14 material handlers 21 front end loaders 38 tractors 15 forklifts and around 155 trailers give or take a few due to weeding out the worn out ones plus countless Hyd. Power units
And by over seeing I mean when the shiz goes bad I go there find and repair
When your working on a million dollar machine with a 90k engine you use a torque wrench
Bend facts how ever you need but torque values are given for a reason.
It's ok to be a jack of all trades master of none Brent just stop forcing your point on I'm old I know better than you whipper snappers the record needs to break. How about we get back to the OP's question
Seeing as he wants to find out why his truck eats wheel bearings anything is game including torque as a culprit

I did
you say torquing is no big deal
I Have real world experience showing otherwise
Yeah I takes prolly 20 wheel bearing bolts to make one of the ones I speak of
torque is torque bolts have a spec to stretch to for max strength, housings can deflect when over tightened in which bearings are seated in turn could cause misalignment. Is that what is going on here guess we won't know until he try's it

Here is a wayyyy out thought
This topic is discussed in more detail in the article, Transient Current Flow, A Silent Killer. Insufficient grounds, can cause the electrical flow through the wheel bearings. Current drawn by the devices on the engine, has to return to the battery. The engine is electrically insulated by the engine mounts. If the engine grounds are poor, current will flow out through the drive-axles, bearings and knuckles to reach the body. This flow will quickly destroy the bearing and several other components, including the transmission. Technicians use a voltage-drop test to locate transient current flow.
