Looks like 4. One on each joint and one where the tie-rod connects to the drag link:

I didn't find any other zerks on our E350; I expected to find them on the u-joints and perhaps the center carrier bearing, but they are all "Sealed for life" devices.
Now that we have a new Chevy 4500, I'll explore & find the maintenance points.
Cheers!
