9.25 rear diff

I measured the backlash on the 9.25 rear in my Ram and its got 16 thousands in play.
Is that enough to cause a decent amount of road noise?

There is 117,000 miles on the ring and pinion.

The spider gears in the carrier look pretty well worn and sloppy.
I'm hoping that's whats making the howl/wine sound.

The wear patter on the ring looks even across the whole face.
I'm not sure what excessive wear looks like.

Any help is greatly appreciated guys.
I'm trying to avoid dropping big bucks on fixing it.
