Driving with torn boots is not an emergency. I wheeled URE in October with torn boots, stream crossings, mud....not a big deal. Big Swede has had torn boots for a LONG time, if you replenish the grease every once in a while, you should be fine. Definitely not a roadside, duct tape, tow truck, thanks to the lord kind of deal. Not to make your situation appear non-critical, I just don't want other folks to freak out if it happens to them.
Looking at your CV angle, you really should look at doing a diff drop, or lowering the front end back down. I am close to stock front height now, super flexy, and I can stuff 34s in there with ZERO rubbing. All I did was remove the splashguard and trim/pound the back of the wheel well. It performs offroad SO MUCH BETTER with the front end lower.
