Possibility that, during a full right hand turn, the power steering pressure lines running to the power cylinder may become scored or partially crushed through interference with a clamp on the power steering power cylinder piston rod. This may result in loss of power assist, but manual steering control would be maintained with higher efforts. Also during a full right hand turn, the left front tire could contact the power steering power cylinder ball and studor its clamp. This chafing could cause tire failure. (install new power steering pressure lines, reposition the ball stud clamp, and readjust the front wheel stops to eliminate the interference conditions. )
