Same exact thing happened to mine. I took the black covers off so it doesn't roll like a busted wallmart shopping cart, but it still doesn't roll near as smooth as before.
I live in PSL and literally 9/10 waves. Especially as you go to the beaches in Ft. Pierce and Jensen area. So much so that my wife is constantly pointing it out if god forbid I miss someone waving. I feel like the jeep culture is pretty strong down here.
