Four wheel drive not working correctly

I was driving into a wash and the ground crumbled underneath my right front tire and I dropped down quite a bit onto my front passenger tire and immediately after I put it in neutral and engaged four wheel drive to back out. Then when I tried to disengage 4-wheel drive I disengaged it the 4x4 light indicator light went out and I tried drive and reverse in 2wd and the engine revved up the car didn't move. I put my foot on the brake put the car back into neutral re-engaged four-wheel drive and backed out the rest of the way. Then drove forward home limping it like in between 5 and 10 miles an hour probably for a few miles on dirt road until I reached my house any ideas on what all could be the problem I know the tire is setback it's touching the wheel well on the passenger side front tire what all do you think got damaged is it fixable.
