Not all HO metal wheel axles are the same length. That's due to different truck manufacturers
that the model car manufacturer uses. |

There are differences in axle speifications between manufacturers. One brand will work with other brands of trucks but may be looser or tighter in another brand. Sometimes you are better off replacing the truck / wheel assembly. For example, the Proto 2000 truck / wheel assembly is extreamly free rolling right out of the box.
For free rolling wheels on any kind of truck, check and clean out the journal box where the axle seats. There may be casting flash. You can use a new #11 Exato blade to clean off the flash, however Micro Mark sells a special tool called a
"Truck Tuner". And, if you don't already have one, buy a
NMRA Standards Gauge to check the wheel gauge (They cost $3.50 if you are a
N.M.R.A. member and buy it from them). N.M.R.A. Standards gauge is available in O, HO, & N scales. Sometimes the wheels are not in gauge out of the box.
Another tip for free rolling trucks is to use a powdered graphite lubricant on the journal box / axle point. Kaydee sells
"Greas-em"
