well i went got the belts and finished up in two hours. i have to say that it wasn't bad at all. i was getting a little pissed off at taking the bolt out. wasn't sure if it had reverse thread on it. (it didn't) after that everything was a breeze. from the time i sat down and got the tools out to the time i put them back up. took roughly two hours. pretty much did everything by myself. had my dad supervise, but did most of it by myself. IMPACT WRENCH IS A MUST!!! IMO
