I had door issues which involved the hinges wearing out. I asked on the forum and got quite a few. I might have some which are serviceable. A tiny movement at the hinge turns into quite a sizeable movement at the door.
Burky's post is an excellent description of the adjustment possibilities.
The hinge against the body has slight adjustment possibilities, both laterally and vertically.
There are hinge shims which can adjust the position of the door laterally (forward and back)
The six bolts which connect the hinges to the door can facilatate this.
There are shims for these connections too. These are shown in the on-line Workshop manual.
The locking catch can be moved to ensure closing too.
Joking aside those little rubber/plastic end caps are crucial - they make a serious change as they force the door latch to the second position easier. They also take a away the "clang" when shutting the door.
My doors were a real problem until I worked out a procedure to get it right.
- Windows down, chrome quarterlight and window guide section loosened (two bolts and two adjustment bolts.
- Adjust the hinges on the body, lateral hinges on the door and the latch to ensure that the door closes correctly and easily.
- Adjust the chrome quarterlight/window guide so that with the door closing correctly, it seats correctly at the top of the body door seal.
- Adjust the window glass so that with the door closing properly and the front window guide seating correctly, the glass seats itself correctly. There are multiple adjustments possible at the rear guide, the bump stops, and even the centre bolts where the lifting mechanism attaches to the glass. Be careful with this though but there is scope for adjustment. I found that the glass process was easiest from inside the car with the door shut.
- Repeat the above about 20-30 times each side.
