Chaos, welcome to the forum. I'm going to tag @Chris A Hardaway in here, he does it for a living and may be able to help with a little more information from you.
Hey! Oakley doesn't sell the little titanium "spring" part. I assume you are talking about the little curved silver piece. If they are over 1 year old Oakley shouldn't warranty then, since it's a one year guarantee. But I've heard they'll normally replace it up to a second year with receipt. If you find another used or broken "parts" transistor I'd be happy to disassemble and reassemble for you.
