Thank timswi for the reminder,
Perhaps I should have put more detail into my post:
1. I too had the squeal the 2nd day of ownership on the 500.
My repair was easy since my wheel came of easily and the seal was soft in the summer heat. After I removed the rubber seal, I coated it with olive oil. It has a non petroleum base that will not cause damage / deterioration to the rubber ring.
This also works good for the weather strip around car / truck doors. (forget Silicone Spray, Armour All etc.)
2. I figured out the wiring plug mentioned and used it to power my Strobe Lights that are described in one of my post's.
3. I to am curious as to what accessory this plug is for? Just trying to get the post back to the original intent.
Perhaps work lights?
Still diggin out,
