Yeah, i feel the same way. About a year or two ago i could not turn a wrench or find the right socket to save my life. My friends did everything for me from axles, springs, brakes, and etc. now at least just from watching and helping them i know how to do those things. BUT when it comes down to something you have spent over $6k on you dont want to actually start to experimenting with it. I would love to do all my own work (would save me alot of money) but i am doing things more and more by the day and a diff is far far down my list.
