Re: Sagging Door
I had the same problem with my drivers door a few weeks ago. The only sensible way I could see to adjust so the swage lines matched between the rear wing, door and front wing were to adjust on the 2 door hinges. This involved slackening the 3 bolts per hinge which hold the door to the inner wing, repositioning the door (a friend helps here - one to position the door, the other to tighten the bolts) and retightening the bolts. However to access these, you will need to remove the wheel + wheelarch liner. This will give you enough room to (gently) pull the plastic wing cover (this trim sits between the wheel arch and the door) and onto the door hinges.
3 other things to bear in mind:
1. Make sure once you have repositioned the door that the door window still sits in the window channel when you close the door. By raising the door, the window might sit too far up and therefore not go into the channel. If it does and you slam the door without adjusting the height the window closes to (this is a door pad off job), you risk smashing the glass
2. The self-same bolts on the door hinge also position the bonnet hinge and therefore the alignment of the bonnet. You may have to fiddle about on the bonnet alignment as well to ensure a good fit.
3. You may also have to adjust the door stop (the bit on the door shut that the door catch grabs onto when you close the door). This is quite simple as it is only held in position by a single bolt. However, the bolt is a torx drive style so be sure to have the right tool.
Hope this helps
