They were all pretty straight forward as far as I'm aware. HOWEVER the antilift kit there at the end will be the difficult one. Here's what Outback said when on it...
" We opted for the rear diff inserts for the rear position over the press in ones due to labor differences (to press them in the carrier must be removed). One rear position was left off, ( I would recommend replacing the rear arms vs just a bushing for the rear positions) and in the front we were able to install an anti lift kit, (whiteline kca334) with the use of replacement bolts and some drilling. The difference between this generation and the one previous is the shank of the bolt for the alk and slightly taller, about 2mm. So now you have a camber/caster adjustable front c arm setup. "
