Those would 2 different adjustments.
Vanagon sliding door adjustment.
Most minivans use a similar system.
All sliding doors 85 and up use the same rear mechanism.
Easiest adjustment is the big bolt on the rear frame center area of door that the latch mates with when door is closed.
Are the gaps in front and back with the door closed about the same width.
Is it leaking at the back.
I have an 81 vanagon.
Good thing i was repainting that cover anyway.
Currently it has a good flush alignment in the front but the rear sticks out around 15mm from the body panel.
To move the door more forward or backward there is one bolt behind the interior door panel that lets you adjust the fore aft position a bit.
The hardest part of the whole process was getting the sliding door track cover off.
Would love to have some advice.
Front of sliding door fits flush with front.
The front and rear gaps are about the same 7 5 7 8mm.
I have an 86 vanagon sliding door that has always had trouble closing staying closed.
I need some advice on how to adjust the sliding door rear side so that the door lines up with the body panel.
Once the rollers on.
I had to pound and pound and pound on the thing with a block mallet to the point i thought i was surely going to bend stuff.
After that door removal itself is pretty easy with a helper.
The placement in the door and the hinge is differnet than the one in the pictures.
