Do a seach on this site; quite a few people have replaced their own. I did several years back, as the towing bill alone would have set me back several hundred--the nearest dealer was 100 miles away. He told me to use a really long cheater bar, and it worked. The trick is holding the balancer down while you crank on the bolt. I fabricated a kind of half-a&$ tool that got me by, but there's a guy in Denmark I believe that welded up a real beauty! He posted a photo back a week or two ago. May be on the Tech Help forum or this one, I forget. You can buy a tool also.
