Most minivans use a similar system.
Vanagon sliding door adjustment.
Next open the door and support it working in my carport i used some tires when i work on the sliding door i use my floor jack under the sill this also allows for adjustment of the door for final assembly.
After that door removal itself is pretty easy with a helper.
Once the rollers on.
I need some advice on how to adjust the sliding door rear side so that the door lines up with the body panel.
The front and rear gaps are about the same 7 5 7 8mm.
All sliding doors 85 and up use the same rear mechanism.
A picture woudl be helpful.
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.
I have an 86 vanagon sliding door that has always had trouble closing staying closed.
The hardest part of the whole process was getting the sliding door track cover off.
Those would 2 different adjustments.
Is it leaking at the back.
Front of sliding door fits flush with front.
The placement in the door and the hinge is differnet than the one in the pictures.
Are the gaps in front and back with the door closed about the same width.
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.
Easiest adjustment is the big bolt on the rear frame center area of door that the latch mates with when door is closed.
Would love to have some advice.
