Happened to me, but luckily overnight when van was parked on drive. Parked it normally, but next morning couln't move it. Turned out offside spring had broken near the bottom which released the tension of the spring and it expanded down the strut/shock and jammed hard against the inside wall of tyre. Couldn't rotate the wheel or move the steering. Luckily it had missed the brake pad wear indicator wire and the brake pipe. Dread to think what would have happened if spring had let go in outside lane of motorway at 70 mph.
More recently the garage spotted that the spring on the other side had broken. In 36 years of owning all sorts of vehicles, never had a broken spring. Now two on same vehicle.
