I've finally decided to install new leaf springs in my '76 FJ 40. I'll probably go with Old Man Emu. The only question is should I try to do it myself, or hire it out? How hard is it to do, and what's really involved? A guy I know suggested I take the truck to someplace that has an impact wrench to have them loosen the nuts. I'm not really a mechanic, but more or less a parts changer. I've replaced stuff like starters and thermostats, but a new suspension system seems somewhat daunting. On the other hand, doing it myself could be a great learning experience.
