Just ordered all the parts and tools to begin this undertaking. So appreciative of all the info here!

All of the Aisins on eBay are very expensive and pretty beat ($200 for a rebuilt set w/o hardware, ~$130 for individual grimy ones), so I'm going for Warns ($160 brand new) and banking on the lifetime warranty.

I'll try to document the process as I go... and hope to not screw it up!
