There is a smart not harder way to remove any wheel bearing, and it does not involve a big hammer. Starts with soaking the culprit with Kroil or PB Blaster in advance and often. There is a hydraulic mechanism on the truck (press) called power steering, use it to start movement, then tap it out. For you newbs, look it up. It involves using a socket and extension(s) placed against a loosened Hub bolt and and Lower A Arm, start engine and turn the wheel. Been there done that with my old 07.

I have used Moog bearings in cars, they seem OK but I have been told by others they suck for bigger/heavier vehicles, like our H3s. Timken is my choice unless you happen across a genuine GM.

Been here and done all this many times lol living in Salt spray 🇺🇸 USA. Se WI.
Multiple hubs later and I can share what works for me.
jmho

Timken = China (average)
Moog = China (decent)
Precision = China = Moog
Amazon = China (cost effective)
Ebay = China (gamble/crap shoot)

And in the end doesn't make a difference. All of them fail within a few years.

And just like that the slight hum is gone! End up getting Moog hub assembly with speed sensor.

First cracked the axel nut while the vehicle is down on the ground, took the wheel and brake calipers off, rotor was stuck stuck, so I just removed it together with the old hub, soaked it with some PB blaster and dropped it on the ground hub bolts down and pop it went. Reverse procedure and was done in about 1.5hrs - might do the driver side at some point soon, might as well.

Great to hear! Extremely happy for you that the old wheel hub wasn’t too stubborn to remove!

Now go enjoy your nice quiet vehicle! ;-)
