I did it myself except the seal install part. Disassemble and clean it all up then slide the new seals on and take to your local Husqvarna shop. That's what I did here (they use the Shivers also). My local dealer didn't even charge me, only took him about 30 seconds each side. Beats buying a tool that rarely would get used. Or in my case by next time I'd have a differant bike and need a differant driver.
