First off, what is your jeep sitting at, is it stock or does it have a lift?
If its stock then you won't be able to get anything bigger than a 31 under there and thats probably even pushing it. as far as your axles go if you have the stock d30 and d35 theres no point in trying to run anything bigger than a 33. Its not a question of if your axles will break but when they will.
