Question: when piecing it all back together, what does it mean if while tightening the drivers side (pinion side) flange (#4 here) the input is easy to turn except for one small section, maybe 3 or 4 teeth on the pinion gear?
Then, if the flange is tightened snug, everything locks up and it can't be turned by hand?
I'm guessing this is that precision shimming aspect that is talked about. However, the clutches were the only thing changed, and everything went back on its respective side. Of the six bolts for the flange, I am able to properly torque down the forward most (input side) 2 bolts and it still turns smoothly with just a tiny bit of lash. The problem lies in tightening the rear most bolts anything more than finger tight.
Is there a likely thing (or set of things) that I could have done wrong on reassembly that would have this effect? I measured the shims, and the thicker shim is on the pinion (problem) side. I believe this means that I didn't mix the shims up.
I'm also not sure mechanically what it means that- as it gets tighter, the resistance starts with a few teeth and lack of backlash. Doesn't this mean that the pinion gear is crooked? Or is there another explanation?
Edit: I just watched a video on setting up diff backlash, preload, and contact patch. I'm a rather visual person :)
This combined with loosening the non-pinion side and still having an issue leads me to believe that the resistance is caused by negative lash and binding of the pinion gear, instead of preload. Is that summation correct?
