This fits here.
A buddy of mine told me today he took his car to the dealer for routine maintenance. Oil change, tire rotation, inspection, the normal X you pay for the checkup. They couldn't get his tires off without ruining the lugnuts so they had to replace them. $322 for those fine little puppies - all 20 of them I think - if it has 5 nuts per wheel. That's a quick $16 buck a nut.
That's ****ing NUTS! Pun intended. 🙂
An automotive lugnut is made by cold forming a round piece of steel by force and spit them out by the hundreds or thousands per hour. Probably cost the car companies pennies each. They ship in bins by truck from satellite suppliers to the automakers. And sometimes they do a secondary operation.
What is happening here; marketing decided they need really nice chrome lugnuts to look pretty, so they stamped a chrome plated cover over the cold formed nut since it's grey and ugly. Over time, the cover expands, and the guy in the dealership can't get a socket and air wrench on the lugnuts to get them off.
Really dumb idea, but they did it anyway.
Another case where marketing overruled sound design and engineering and the customer eats the cost of their greed, stupidity, or both.
