1. Check to see that both wheels are driving in both directions.

In checking to see that a No-SPIN is driving both wheels, the driving test should be made under stress so that some torque load is on the driving clutch teeth of the No-SPIN. One way to get this lad is to drive up against a solid obstruction (in loose dirt or gravel, if possible) and see if you are able to spin both wheels in both directions.

2. Check for proper camming action on both sides and in both directions.

On a flat surface with good traction conditions drive the vehicle in a tight circle forward and rearward to the left and to the right to be sure that the outside wheel is free and the outside tire does not scuff. A clicking or indexing noise will be heard.
