Mechanics can’t agree on this one thing

Why is this old-school grease packing method so highly controversial?! 🚀⚙️
There is a massive debate happening in the automotive repair world! Modern mechanics claim you need an expensive pneumatic tool to properly pack a wheel bearing, but old-school traditionalists argue that doing it by hand is the only way to guarantee your wheel doesn't violently snap off on the highway!
When installing a heavy-duty tapered roller bearing onto an axle spindle, it requires perfect lubrication. In this controversial video, the mechanic violently plunges the steel bearing directly into a bucket of thick red grease! By aggressively squeezing the lubricant by hand, they physically force the grease upward between the metal rollers and the inner cage. This scientific process entirely displaces any microscopic air pockets, ensuring the metal parts are completely coated in a hydraulic barrier that prevents catastrophic high-speed friction and overheating!
