I get how the UV damages the parts, but how does a LCA bushing get much light on it?



It's not just the light, it's just that UV is the hardest on it.



Maybe we have stumbled on a giant undercover urethane conspiracy .

In my case I could never pinpoint a cause for urethane caster failures, some wheels were never in daylight, nor wet, some just sitting on shelf never even being rolled, some not bothered were near welder, with stray UV and Ozone exposure, oddest thing to me was how they all died at same time, kinda like how fire ants all bite at the same time.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
