X2 this is the best way to do it!!! I do both of mine every oil change. I put on around 60,000KM a year though!I use a 3/4 drive ratchet and extension with a 1 7/16 socket and i have no problem. the socket is a little loose but im thinkin 1 3/8 will fit direct. the stealership says every 20k. thats wat i do.
My old 6.0L was easier than the 6.4L. Not as much wiring in the way on the 6.0L on the primary filter.I changed mine on my "05 so I dont know how much the difference is on the newer 6.4 but pretty much what everone else has said holds true. I used the 36mm with no extension and it was actually pretty simple, not easy but simple. Your arms get tired even on a creeper so dont think its a 10 minute change unless your a pro.
