Wheel hub assembly question?

I have replaced my assembly one time and that was when it went out after 100,000 miles. Now I have 200,000 miles on the ones I replaced that was after market brand.I have no idea why yours failed.

You can use power tools to remove the old one, but hand tools only to install. Clean the splines on the axle shaft with a wire brush and lightly coat it in oil before passing it thru the bearing. Debris and rust will cause an inaccurate torque setting on the nut. I had a car in the shop with the same problem. Wheel bearings would alternately fail every six months. It took me a few days to figure out that it was a faulty engine ground. Being mounted on rubber engine mounts, the engine would ground itself thru the trans, down the axles to ground. Every time the engine started, it would cause a tiny arc point between the ball bearing and the race. Eventually, the race was rough enough to cause failure.

There are two major causes of wheel bearing issues:

#1. Buy American made Timken Wheel bearings fron Carquest /or/ SKF Wheel bearings from NAPA.

#2. Major Cause: Not tightening the BRAND NEW FROM A CHEVROLET DEALER center hex Jam nut with a torque wrench or air 1/2 impact!!

Is your truck lifted with big tires and wheels on it? That can cause severe stress on hubs and bearings. Next up would be poor installation. Incorrect preload on the bearings will do them in every time. Or you're using junk parts. When you say hubs do you mean the actual hub or the bearings and races? Oh and why did you ask this SEVEN times? Post it once and wait for answers please.

The answers don't changed just because you didn't like them

My guess would be faulty installation or crappy cheap parts. I have NEVER EVER in my 25 or more years in the automotive business ever seen a wheel bearing fail that early. I always used GM brand parts & have never seen them fail that low. Either your using crap parts or from faulty installation. They need to be installed flush as well on the knuckle, make sure no corrosion or rust is on the knuckle. Get sandpaper to smooth it down

And no wheel spacers, very bad on wheel bearings
