Awesome, I just graduated from UA last week. I'm from here though, so t-town gets a little boring for me...
It was actually really easy! I don't have a LOT of mechanical experience, but I do like to tinker with my friends' & my vehicles so I'm pretty good at figuring out how this stuff works but I am far from a trained mechanic. I have only pulled coil overs off of a vehicle once before (a '96 t4r a few months ago). I did it bassackwards that time and compressed & removed the spring first instead of the whole coil over, then the spring. Of course I had no instructions then and was just going at it head on having never even looked at a coil over shock before (obviously it was before I found t4r.org).
Like I said it took a little less than 3 hours by myself and the only specialty tools I needed were jack stands, an air impact wrench, and a loan-a-tool coil compressor (though I've read it can be done without the last two), I don't know why some say you need a ball joint tool. I don't see where it comes into play, everything came apart easily for me. [Of course my runner is in pristine condition and I couldn't believe how clean the frame, skidplates, suspension, & underside of the motor were.]
I think if I did it again I could do it in about 1.5 hour, 2 at the most. I would recommend carrying a laptop or printout of a writeup from here or another forum before doing it for the first time because I forgot a few simple tips I found that would've made it even simpler.
