The gears on top of the chassis were well lubed with white grease on my 4 gears. It's just the axle ring gear contained within the chassis that was dry. And yes, they are excellent runners once broke in.I have to say I just got a bunch of new AW Ultra g's 3 gear AFX type of chassis's from Rob aka Bud's HO and they all came loaded with white grease all over the plastic drive train. These cars are seriously excellent running. ANd quiet!!
