2004 Chevrolet Impala rack and pinion

rack and pinion without Magnasteer do need this since I just replaced inner and outer tire rods

Can you explain what your problem is? The more detail the better.

Are you asking if you can remove Magnasteer, the variable steering power assist?

Just replacing ties rods means you replaced a small portion of the steering system. You haven’t described anything else about your car or the problem. So Yes, you might need a rack and pinion.

I replacing the rack and pinion on my 04 Chevy impala ss trying to find out the right part found one

Is it leaking?

Is the steering binding?
