If youtube is your yardstick then we should also discredit all old authors, teachers and also entire libraries.
Now lets see, your buddy Kilmer has an ancient video of a rear wheel bearing replacement on an avalon, (same as all fwd toyotas) because its old its a cartridge type replacement where you have to put the stub axle into it (requires pressing it off and installing it on)
He just makes a grunt sound and calls it “make sure its tight” while the actual value is 85lb/ft on the stub axle nut (toyota mention such in their “service book” and not a youtube video.
Now imagine if someone who is anemic and 90 lbs weight is asked to make it “tight with a grunt” and he follows that the guy was using a standard 9 inch ratchet vs a burly railroad mechanic who is using 3/4 drive tools with a minimum ratchet length of 20 inches and going to the “grunt till tight” torque.
In both copycat cases the bearing fails. The torque sets the bearing crush preload and toyota used the industrial specification for that size bearing of 85 lb/ft, too bad people like you wont ever understand it because toyota didnt produce youtube videos of it. Undertorquing can cause walk and over can cause damage to the rolling elements or the stub threads.
Applying knowledge to an application doesnt mean you can execute a “monkey see monkey do” type job, the difference between quality of work is doing the job with the tight tooling and the right knowledge too. Just like when dumbasses show up in Pakistan claiming to be ac mechanics and have no idea what a vacuum pump is or even know of the words called superheat or subcool.
