I can't recall how many times I bled on friends' Jeeps trying to keep them in running condition (or modifying them) and ready for the next off road adventure; and no, not mall crawlers--buried over the axles in mud muck and unidentifiables flowing around your feet hoping you didn't just suck water, dragging others out of the same said muck, navigating places where angels fear to tread, spending hours cleaning and reservicing axles, t-cases, and zerk fittings to make sure you didn't ruin something (learned the hard way)
