I don't like to interfere with the camber.
I don't think its a lot of extra work. Undo 2 bolts and remove brake caliper (I usually support it with a length of lock wire to prevent it from hanging from the hose), Disconnect steering tie rod ball joint (I have a seperator that makes it easy) and undo the lower wishbone bolt.
Ok you just undo 2 bolts and leave the hub in place but I've never yet got that camber angle spot on subsequently and have had to have the geometry redone.........for the sake of 10 mins, I'd rather do it my way, but hey, each to their own..........I used to do it your way
