Ball Joints

What is your question?

I was at a tire dealer to get a front end alignment. He told me I couldn't get an alignment because the ball joints were worn out. I got an estimate from an independent repair shop to replace my front end lower ball joints. The technician told me I had to replace the upper and lower ball joints and the "frames" that came with them all at the same time. I am skeptical about this. Is all of this replacement necessary?
