Maybe not just Athearn, as I have a set of Wiseman trucks that do the same thing.
Here's what I've got going on: I'm using Athearn archbar trucks and Northeastern wood bolsters on some cars I'm building. The cars lean with the trucks mounted. I can use my finger and push the car and it will lean to the other side. The car doesn't want to stay level sitting on the trucks. The bolsters and trucks are centered on the car.
Anybody else have this problem, or a solution to the problem?
