That's an Athearn loco - they originally called it an SW1500, but it's not, and it's not the oldest version either, as it has inside bearings and plastic sideframes. Looking at your third photo, the problem is obvious - you're missing one of the bearings. 
I'm not sure if you can buy the bearings separately, but they're very easy to replace.
I just had a look at the Horizon Hobby parts list and didn't see any axle bearings listed. However, they do have a replacement truck in stock: Part #ATH41024 Front Truck, for $10.00. Make sure you order the front truck, as the two trucks are not the same.
