Today the sliding door on my Aero began making a cracking noise as latch was opened. I think its the upper jaw on latch assembly snapping open. Lubrication made no difference. I can created a bit of lateral play at latch point when door is closed but door stays closed. Any ideas?
I have never heard of the latch going out before. Have you checked the condition of your striker Bolt? There is a plastic bushing on there that tends to wear out over time. A replacement can be found at any auto parts store.
Another part that could be causing your issue is your lower roller. Very common wear part.

That is what my bottom roller looked like. Once I replaced it the door opened and closed a heck of alot better.
A agree, the lower roller can cause all sorts of issues with the latch by putting additional strain on the parts. If ignored, it can break stuff. All of our Aeros have had the lower roller replaced. It is a wear item. Keeping the lower track clean helps it last longer. Great pics there nighthawk, that really does show the difference between old and new. When it wears out, the whole door sits 1/4" too low, which prevents the latch from lining up properly.
I'm going to try striker bolt cover and lower roller(well worn by the way) but I can duplicate the noise by loading latch jaws against spring tension with a finger and releasing. It seems to be generated by jaws against latch case or against something internal. Probably much ado bout nothing.
I had the same problem with my '93 Aero. I replaced both the striker bushing and the roller with parts ordered through the local Ford dealer. Getting the old roller off of the bracket was a nightmare but the job got done and the problem is solved. No more cracking and dragging, at least when operating the sliding door.
I'll give my local Ford dealer a try on rollers. I replaced mine with marginally better ones from junk yard. Still needs more vertical lift to get alignment correct.
I have the perfect bearing for the slider bottom roller that wears out..

Its the perfect replacement. A little higher and it should never wear out. Smooth as glass.
Did all my vans..I think I locktited it to the shaft..can't remember.
I ordered bearing suggested by 99f350sd for lower roller on side door. For the money....... then I got to thinking that the factory roller may be a sacrificial wear item. Either the roller wears or the track wears. I'm sure the metal in a roller bearing is a lot harder than the track material. Think this is a problem?
That would certainly make sense. How does your track look now, with the roller worn out? The part of the bearing that would ride on the track is the outer housing, which is probably not nearly as hard as the journals, but still harder than the plastic roller. You don't want it to act like a pizza cutter. Of course, you can weigh that against how long you plan to keep the van.
Original roller had not quite worn through; junk yard replacement slightly better so track looks good. My Aero is used as a work van; lots of saw dust and drywall dust. I blow out track/step area weekly; lube monthly.
How long do I keep the van? Til some auto maker offers a suitable replacement. Sprinter too big for city parking; Transit Connect is too short and can't tow my 3500 lb hauling trailer.
Back to the subject at hand, I'll give the bearing a try and keep an eye on it. It may not have enough traction to roll through the dust/crud but the price is right.
