I think the pinion is still in to deep. BUT before you change it bring the back lash down a couple of thou to .006-.007 and take a look.

When doing rears you usually need to move the pinion shim .003 to see a difference.

I wish i could stay up and help you but i'm east coast!. good luck here i just found a link on line of pics to help you out:
