No noise in a straight line only when the car is turned left or right going forward or in reverse
Its a ford 8 " with new gears and limited slip . Its even difficult to push the car by hand if the wheels are turned.
Almost feels like something is binding.
Get the back end up on car jacks with the front tire blocked (safety first, squished forum members is a bad thing). Inspect the brakes, verify the parking brake can fully release, then rotate either wheel to see if there's binding.
