Rear Brake Line is Leaking :( does car have to be complety lifted?

[SVXgarcia]

Unfortunately the leak is coming from underneath subframe or frame. the leak is not directly visible but Im guessing the only place it could be leaking from is the hardline that's burried under car since I can see all the brake fluid dripping. Does the car need to be lifted off all four tires in order to take the rear end apart? Has anyone here attempted this before? any advice?
Thanx guys
