Time to pull the winches and disassemble them for cleaning. Warn is not a fully sealed winch. While water will drain out, mud will not. everything is pretty simple in there. If you need some pics for assembly, check out warn's website and you'll find it. Don't forget to grease everything up upon...
I can't help ya out with parts. But i can say, look for a ZX chassis headlight. fits and way cheaper. The factory 800 Rev Summit pipe is way better then the SPI. It's also not prone to the Zoomies (hot/cold pipe).
