From Pathfinder Wiki
When the wheel is placed on the axle and the axle is inserted into the car, apply some graphite lubricant into the wheel's hub and spin the wheel. Once assembled, it's a good idea to spin each wheel for as long as you have the patience. This works the graphite into the joint and lubricates it. You can spin the wheels by hand, or rig up a device of your own invention do do it for you.
