Spindle bearing spacer

I call bullshit. This "setup" has been in use for decades and decades. Can you spell "more than a century?" These setups WORK. All you need is a simple adjustment and proper lube and they go 10's of thousands of miles. In some cases 100K.

This design was also used for decades on front and rear axles of 4x4 pickups AND IS STILL IN USE on drive axles and steering and tag axles of heavy over the road trucks.
