THE CIRCUMFERENTIAL WELD AROUND THE STEERING SHAFT TUBE THAT WELDS THE SPLINED TUBE TO THE NON-SPLINED TUBE MAY BE MISLOCATED. MISLOCATION OF THE CIRCUMFERENTIAL WELD MAY ALLOW THE SPLINED TUBE AND NON-SPLINED TUBE TO ROTATE RELATIVE TO ONE ANOTHER DURING A LOW SPEED, HIGH TORQUE TURN, POSSIBLY RESULTING IN A SEPARATION OF THE TWO TUBES.
