Great! I watch it several times. I realize taking the breaken down parts of the engine to a machine shop for cleaning and machining could save me time and perhaps money, but I'm very much interested during the job myself, at least for the first time just to see how its done and the do-it-yourself hand tools, just to get the feel of the amount of work and precision involve. I did some homework, and realize rebuilding a engin (cleaning and machineing)is not a rush job or a hour or two event, it would take several days and depending on time available.
The Differential Rebuilding DVD was a complete, through, and very informative lesson. After reviewing the DVD, there's no doubt I can rebuild my differential. Excellent! in my book.
