I have a stock 87' XJ with off road tires. I plan on going up a trail but there is one really bad section that I haven't had the balls to drive through. Its washed out completely. I'm afraid of dragging the differentials. The middle of the trail is gone. I have a hi lift Jack and a 4 ton hand winch. What do I do? (I'm also 16 so I'm not very competent)
