Coupling rods or main bearings on wrong centres at the tops of the axleboxes maybe? You could try taking out conrod pins or axle boxes one at a time to isolate the problem. (or one conrod at a time.) You may need to loosen up fits in the axleboxes, conrods, or both to allow for the spring travel and eventually rough track. The real thing had lots of clearance for smooth action.
