I just got some 32x11.5x15's for my TJ. It only took one trip over the hills to the coast to realize that I need new gears. Luckily I've got a D44 with 3.73 (It would have REALLY SUCKED getting over some hills with anything less)
My real question here is what gears do I need and how hard will it be if I change them myself? I don't see extreme rock crawling in my future but there will be some moderate trails.
As far as my mechanical aptitude goes I would say I rank fairly well (No problem doing engine, tranny swaps, etc.)
Any help you guys can give will be great since I have my accountant (wife) talked into this so I need to get something before she decides that money is better spent on antiques.
