Question about giraffe (actually a rhino) car

Deuce, I don't know how loose yours is, but there is a little bit a play there normally. The issue, I think, is that the car is on the lightweight side. You could experiment, by snapping off the box car shell, and place some small weights on the frame of the car nearest the side of the rotating gear. This is what I did on mine.

If you don't have any self-adhesive tire balancing weights (which is what I like to use), you could try some steel washers or nuts. See what works best and then you can glue them or duct tape them into place.

Also make sure you've got some plastic safe lubricant on both gears.

Thanks! I'll add some weight and report back.

There are 2 versions of the worm gear on the axle, plastic and metal. which one is yours?

Plastic

OK, the plastic worm gear is actually a larger diameter than the metal one. There are loose as you describe. They work best on flat track. Have you reversed the car in the train, so the worm gear pushed from the opposite side?

I have, and it works better, though still not as consistent as I would expect. Guess it's just a "design feature".
