Wheel Alignment

Left Rear Camber -1.1 Left rear Toe -0.14 Degrees Right Rear Camber -1.5 degrees Right rear Toe 0.01 degrees Total Toe -0.14 degrees Total thrust angle -0.08 degrees. Is this acceptable if I rotate my tires every 6 months faithfully or do I need to spend the estimated $1,200.00 at Nissan to replace rear adjusters that are frozen and won't turn and bring into tolerances. Can the adjusters be freed up any way or once frozen replacement only option? Thanks!
