Should I keep chasing it? What direction next? I'd guess a little thinner pinion shim, maybe .005" more out... What backlash should I be shooting for?

Looks like you're goin crazy and this is just my opinion.
I'd go back to # 21 set the BL at .10 and run it .
What brand gear is that ??
I'm still at #21... Backlash is at .008. These are brand new Strange gears and new bearings. If anything I was going to pull a bit of pinion shim out, but if deep is the recommended setup...???

I am a big fan of a proper pattern, i hate noise from the rear and the vibration it brings with it.
I see the drive and coast are now on the same part of the gear so you are real close. Can you have someone with a lot of pressure hold a prybar between the case and the spool while your turning it so it cleans up the lead and gives us a better look.

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: http://www.precisiongear.com/pgtechpatterns.htm

Pulled .005 pinion shim out, putting me at .040 pinion shim, .052 preload shim. Backlash was at .007, now at .009. Drive Coast

I just called Strange, and they said .005 - .009, with even .004 being OK since everything is new. I'll swap .004 carrier shim which should move me about .003.
We'll try again after work.
Thanks for all the help guys!

Attempt 23 - Moved the carrier into the pinion by .004. Backlash is now .006. I'm just about "done" with this thing... in one sense of the word anyway. Drive Coast
