Note the side of the truck where the end of the axle is. On the right is a round plastic cap with a triangle shape on the end. On the left that piece is missing. What is this part called, and is it common for them to go missing while a car is in shipping? I just ordered this caboose from Grybowski trains and it arrives with four of these plastic pieces missing from the two trucks. One part was still in the box, so now I need three. Does anyone have any experience with this happening to them? Will Lionel just send replacements, or do I really have to ship this whole thing back for warranty? I'll have to call Lionel on Monday.
