Bachmann HO Doodlebug gear lubrication

[RobertRent]

Please excuse my novice question.

I purchased a Bachmann Spektrum HO Doodlebug and want to check the gear lubrication in its main truck.  To do so, it appears as though I need to remove truck's bottom cover (see below image ) by prying on it, but I am afraid that prying will break the cover.

Can one of you kind forum-dwellers tell me how to remove the cover without breaking it.  Do I pry on the front and rear tabs or the two slotted side slots? The side slots appear to be the appropriate ones but they have protruding, soldered wires.

Or, is my thinking flawed and I instead need to remove the entire truck assembly, or somthing completely different.

Thanks in advance for any advice, RobertR

Is it possible that I need to remove the entire front truck assembly in order to access the gears? Per: https://forum.mrhmag.com/post/repowering-a-bachmann-doodlebug-with-a-kato-power-truck-12247660
