You'll never make a crooked swing straight.

If the Frame is crooked its no good shortening a rope here or there, the Swing will always be crooked if the Frame is crooked.
You need to make the crooked Frame straight, by digging in a leg or two (or three).
Remember that all swing frames sink through the turf anyway, so to level a Frame on a Crooked lawn you have to dig into the soil proper.
