This happened to a fried of mine. He was driving his Dodge Dakota and well...long story short hit a curb completely horizontal, as in he completely slid into it. Bent his entire frame. His truck is still driveable but his bed and cab sit lopsided. It almost looks like he's driving at an angle. Although he never took the time to get it fixed (or checked out for that matter), it's been this way for about a year now and besides the driving slightly sideways, everything else runs fine. His 4WD still works too. If needed i could try to get a pic and you could compare it to yours.
