I only have a Christmas Layout so each year when i get things out of storage I like to grease and oil what needs it. I am confused, and have been, on what to do with car trucks where the wheels and axles are one piece (they move together versus the wheels spinning on the axles). It doesn't seem like a good idea to use light oil, the kind I use on wheels that turn independent of the axle, since the axle is turning in the plastic side frame.
what is recommended in these cases?
As always, thanks.
