One of my fenders and my header panel are destroyed. There is difficulty opening both the doors because they rub on the fenders (I have a 2 door so on the other side too.) It looks like the fender on the side opposite of the collision is bent in. Here's a picture:
The hood got shifted. Could this cause the bending of the fender on the other side? I can still drive it fine.

 

Post more pics so we can have a better chance to help you assess the damage. Full front and both sides.

 

looks like the fender got pushed in a little, you might be able to pull the fender out so it will clear the door when opening it

 

Like winston said post some more pics cause its hard to say. When I got my jeep at auction it had been hit in the front but never got into the jeep having the body bent. If it still drives straight and doesn't pull left or right i would say probely not but its hard to say.

 

Here:

 

Was this a direct front hit or from the side? Did you remove the bumper or was it torn off in the accident? A side impact that tears a bumper of will most likely damage the ends of the frame rails, but it may not be to severe. Pic of the bumper mounting points would be very helpful.

 

I was swiped from the side. The bumper was torn off. The mounts were just torn off, tearing the metal.

 

Then you are probably ok. Just to be sure I would have a body shop inspect it and give you an estimate. Almost every body shop out there will do estimates for free so you won't be out any money and will get a definite answer.
