Awesome write up. Thanks a bunch. I did this today, after reading through your step-by-step, and I didn't even have to refer back to it. I had my brother to help, and an extra set of hands made things go much smoother.
We will do my brother's over Christmas (also an '05 LGT LTD), and we are going to try to set a record.
Just a note. Getting the pulley off is the hardest part. Impact wrench wouldn't fit. We borrowed my dad's BIIIIG pipe wrench. I think the handle is 3 feet long (no joke). We wrapped the old belts around the pulley to protect it and held it in place with the pipe wrench and broke the bolt loose with a cheater bar. I know most people don't have access to a pipe wrench that big, but if you do, it works like a charm.
