HEEELLLPPP!!! H2 is now lower on one side

[coach3rd]

2005 H2 does not have air suspension. My son ran off the road the other night and hit something hard enough to break the rear shock in two. Both front and rear wheels went off the road and in a ditch. No body damage just seems to be lower now. Only the passenger side went off the road and now the H2 is 2 inches lower on that side (front and rear). I replaced the rear (passenger) shock and have looked all over underneath and cannot find anything else broken. Also there is about an inch of space now between the rear (plastic) bumper and the rear quarter panel. The ride is fine except for the 2 inch lean on the passenger side. What else do I need to look at. Is the frame bent?
