What do you mean by "won't turn in unison with other wheels"? Turns at a different speed? Different direction? It sounds like the left rear spindle is bent and that wheel is steering to the right. That makes the rear of the car go to the right and the front steers to the left. You have to compensate by turning the steering wheel to the right. You're turning the front wheels to match the rear wheels.
On an alignment computer it is the left rear "toe" that will be wrong, and that means "total toe" will be wrong. Total toe simply looks at the two rear wheels together and that number is critical for good tire wear. Right now your rear tires are pointed closer together on the their fronts, kind of like a V-shaped snow plow going down the road. That is going to scrub off the tire tread on both tires. You'll see the horrendous wear patterns on both tires equally if that isn't fixed.
