It is ...
Most awkward thing for me was re-fitting the HD springs ... same size as standard, but stronger wire, so harder to lever back in. We eventually used the disco bottle jack between the axle and chassis to spread it a little more. Gotta be careful, as T says, about the brake lines, but if like mine yours has anti roll bars then it doesn't droop fully if left to do so by gravity.
