I have the hf tire changer. I did some welding on it to make it stronger. It works real good. I have changed a ton of tires with it ranging from small car tires to 75 lb truck tires. It does them all. Use some lube and its a cake walk.
Good to know. I too would beef it up a bit. You could save some money mounting and balancing yourself. It sounds like this method is superior to spin balancing and lead weight on the rim. I spend a lot of time in the mud and snow and the balance always seems off when you get on the highway. The stock rims on my late 90s dodge trucks have a nice pocket for dirt to collect. Sounds like the dynamic self balancing will be just what I need.
My 98 has over 250k miles on it and definatly has some worn stearing components. It's slated for a front end rebuild soon. My 99 is still tight at 150k miles.
