I had mine all nicely aligned a while ago by my local Ford service dept. I rang them and they said bring it in and 15mins later out I drove. The front has to come off to replace the globes but does not need to be removed for alignment.
Probably doesn't help too much but look at a workshop manual - they've usually got instructions to do such things
