Default Adjusting pinion angle process?

Damn is pinion angle a mother to set. I was at a positive 4 degrees so I am trying to make adjustments. I have unbolted the sway bar,lower control arms the t/a from the top diff and bottom diff. I have also loosened the front t/a joint but still have the bolt in it. What is the order of adjusting it and am I going about this the proper way? At this point I have the pinion angle set at -2 but everything is still loose. Please explain to me which I bolt and adjust first as there are many adjustments to be had at all the joints. I need help like yesterday It's on the alignment rack at work.

put it all back together and adjust the bottom of the tq arm, while your gauge is on the yoke.

Maybe Eric will jump in here.
But I would bolt everything back up loosely.
Adjust your ta to fit your upper and lower diff, run the heim joints in as far as possible to get them to fit. Bolt your front heim joint in by adjusting the front heim joint.
Adjust and tighten your lca's, phb, and sway bar ends.
Find your ds angle with a protractor, then set your diff angle 2 degrees less.
There's a flat spot on the bottom of the MWC rear, put your protractor there.
Then adjust your diff with the lower heim joint on the ta.
Most of these cars the ds runs downhill from front to rear, 1 or 2 degrees.
If your ds is 1* set your diff at -1*. If your ds is 2* set your diff at 0*.

Now I have been drinking since 10 this morning.

A big part to what i think was is the problem is that It was at +4 degrees and my front ta joint is on the highest hole. When I moved the lower nut on the diff to adjust it did not move much and required excessive force to keep turning. I just stopped and started unbolting things until it moved easier. Now I think my lower adjuster is too far adjusted.
So basically I need to redo it this time gonna (1) lower the front ta joint lower (2) run the others on the diff closer in(3) and adjust accordingly.
How many threads on the front one for a starting point?
