Upon great frustration and stubborn-ness i was able to figure it out.
Now the fine degree of back lash is not perfectly in spec. And everything is golden, spins like a top everything is beautiful.
How you might ask? Well first we should ask how come i did not do more reading on the internet all about doing something like this.
Cause i have blonde hair. Terrible foresight and 20/20 hindsight.
With the self insults out of the way. Upon reading the links that dudeman provided me and just more just wrapping my head around it all(not much to understand, very straight forward once you get it all...esp cause i am kicking myself for not doing what i did today) I was able to come up with a few reasons why it was 'binding' on me even tho the backlash and runout were in spec.
Well i took all apart down to just the diff and ring gear. Whipped out my trusty dusty set of semi-shitty 'OEM' calipers, and measured everything again. And upon realizing that my two thrust washers were two different sizes(even though when i first took it apart i measured them and realized it but it held little value cause the difference one was .3 mm and i did not actually "understand" how it would effect everything) I had an epiphany.
Well one thrust washer was .3 mm larger than the other. and of course that one was on the ring gear side, thus pushing the ring gear .3 mm further again the pinion gear and creating some minor binding. I guess some how when i had all the parts out on paper towel as i was working everything they got swapped between the sides. So i put .3 mm larger thrust washer on the other side, and the smaller one on the ringer gear. Thus it adjusted the ring gear .3 mm away from the pinion gear and freed it of it's binding. Checked everything twice and everything is 100% in spec. And it is operating correctly.
I guess what i learned that even if it so painfully close to spec, if it is off by just the any conceivable amount then there is a problem. The runout was 100% def in spec and the back lash was so just barely off before.
Well i learned a lot. I now know way more about how a diff works than i did before(and i know still plenty more for me to learn
) and for the i could not be any happier.
Thank you again for everyone who provided help/advice or anything(facebook included; this was too long for facebook).
