Michael - I really appreciate your opinion. It certainly seems to me your are correct becuase as I think about it, if it was such a nightmare then why make it a regularly scheduled maintenance right? If Isuzu says do it, it must be required. I do know my friend is "cheap" - no offense but he always professes this and is trying to save a buck whether it buying a car or used tools. Regardless of how or why is maintains such opinions, I will tackle this and let you know before I start - I'll be counting on you and the others for any help!

Alos, if you can, take a look at my questions 2 & 3 above regarding shims & tool drivers, I just want be as prepared as possible. Thanks!
