Turning problems?

As of yesterday, everytime I make a turn either left or right my truck starts jerking around and the tires kinda skid, like they don't want to move and takes it a couple seconds for it to finally move. And when I hit a bump it flys around. I thought maybe it was the all the snow build up around the tires causing it to do that but I cleaned all around them and it's still doing it and I don't know what's wrong with it.
