I'm sure this is covered somewhere, but I seem to find more info on the
latch mechanism.

My problem is that when I open my door I often have to pull the back end
out a little bit in order to keep the back of the door from hitting the
door frame as it swings out and slides towards the rear of the van. It hits
the corner of the door frame when the door has opened just an inch or two
and after that there's plenty of clearance.

Does anyone have a fix for this?  Is there an adjustment or a spring I can
replace without replacing the whole mechanism?
