I just did mine (300SD), and boy, it was a lot harder than BobK makes it sound. Maybe I had the wrong wrenches but I had to disassemble everything in sight because I couldn't get to all the turbo mounting bolts, I could get to three of them, but could hve just saved myself the time and commited to pulling the manifolds. It's like on of those puzzles where you have to dis- and re-assemble everything in a mysterious sequence...
