SPRING LOADED CROSS STEERING TUBE BALL ENDS. Origin. To provide cross steering tube ends that will not require adjustment, and to reduce road shocks. Experimental Test Report. Using the strongest spring given by WW. an appreciable amount of friction is gained in the steering. We believe considerably more damping would be beneficial with the new axle. Road Test Report. Run 10,000 miles on 12-EX. The initial spring loaded movement was removed as this was found to be better for wobbles. The extra friction improved the steering. Weight of Old Part.
