ok ok, I'm new to a K5, can someone please explain to me about the front hubs. When or why would I lock them? At the min it's snowing and icy here, the hubs are locked all the time, is this right? Sometimes when trying to turn sharply into a parking space the whole front end jumps, is this because of the hubs being locked? Just doesn't like turning sharply, someone please explain the hub thing to me.
