Just my 2 cents...
My '01 Box just hit 60,000 miles so it was time to do this job. I found it easier to thread the belt through everything except the bottom left idle roller. That way I could make sure that the belt was already seated into the grooves of all the other pulleys.
And yes, this an easy "3 out 10 difficulty" job. The belt cost me $31.80.
My only problem was not having a 1/2" socket wrench to do the job. It's harder than hell to find a 15/16ths socket for a 3/8ths socket wrench. Don't get an adaptor for the 3/8ths wrench. It'll only make it too long and you won't have enough clearance.
So now I have a new belt and a new 1/2" socket wrench!
