I spent some time rebuilding my Warn model 8274 and thought I'd share a bit about my experience. I knew nothing about these winches, but with the help of the below five sources was able to complete the rebuild fairly trouble free:

My WARN 8274 rebuild part 1..... | IH8MUD Forum
The whole rebuild is something anyone who played with legos as a kid can complete. Upon inspecting my winch I decided to put a lower housing rebuild kit and a brake rebuild kit from amazon on the unit. I also have upgraded my motor to the 9.5xp. The 9.5xp is literally a bolt on unit, nothing more to it than that. The motor came with a gasket and a washer as well..I had to make an educated guess as to where the washer went...if anybody knows where it is intended by warn to go please chime in below
Winch before I tore into it:
As you can see in the second picture it looks like the tabs that connect the upper and lower housing broke off at some point and were welded back onto the housing..Not sure what would have caused this to happen
The only grief it caused me was that the upper and lower housings were not a perfect machined fit when retightening the upper housing to the lower (It might be that these upper and lower housings are never quite a perfect fit) so I made sure I got the drum lockplate into it's slot in the upper housing and called it close enough.
