How are modern wheel bearings so good?
Their assembly is the same 2 tapered roller bearings used in cars from 50 years ago.
Yet they last way longer.
What sets them apart?

Look up Dr. Harry Badeshia's work. Dr. Larrin Thomas also has a lot of good information on metallurgy published publicly.
WPC treatments.

>>28496137>>28496117 (OP)Metallurgy and petroleum/lubrication science to make grease that stays good for longer. Shit that I don't even pretend to understand. How the actual fuck is my 2011 Ranger rolling around on original wheel bearings at 170,000 miles? If you told someone that 30 years ago, they wouldn't believe you.
>>28496117 (OP)materials science has come such a long way it's actually pretty crazy (and satisfying) to see how far we've come. it's always interesting to see older cars get restomodded in ways that retain the original designs while taking advantage of half a century's worth of technological progress in materials and manufacturing
The only vehicles I've known to develop bearing problems were owned by people who refused to use torque wrenches or do suspension part replacements when the bushings wore out.
Yes, hand cranking your lug nuts is stupid. 100-110ftlb you will find is far, far less than what you'd always been overcranking with a lug wrench. Or the dumbass mechmonkeys have been doing at the tire shop.

>>28496137Not just the materials, but improved machining tolerances.
