I like to take an old or new inner pinion and take some ID out with a die grinder. Makes it a slip fit for easy mock up. That's the only way to go IMO. I have a matching outer pinion as well. This will solve all your problems. I've always used the pinion shim to get your pattern right, and the side carrier shims to set your backlash. Meaning, if your pattern is bad, then moving it side to side ain't gonna do ****.

I iterated twice on the pinion shims, the first two are drive and coast at +6.5mils from the stock shim, 8 mil backlash. The stock shim was 0.029". The second two are drive and coast at +9mils, 7mil backlash. At least they look different. . .
That grease/oil/paint is hard to see to me and its easier to find a sasquatch in NH than it is to find car parts (gear marking compound in this instance) so I used some of that red gooey disc brake quietner spray and re-did the pattern for the biggest shims:
I'll clean the bearings and diff with mineral spirits and then toss them in the parts washer when I get finished setting this up.

Get brake parts cleaner, it can be used to hose the gears off very quickly. Use gear marking compound. Permatex makes some its called Prussian Blue, and should be available at an auto parts store though its getting harder and harder to find these days. Get a small model car brush from the craft section at Wally World for the application of the grease.

I had been trying to get Prussian blue for a couple of weeks around here to check some mating surfaces, but you're lucky if you can get blue permatex gasket maker or anyone that even knows what it is around my house. . .dumbass couldn't find me a pinion bearing under FRONT WHEEL DRIVE. . .gotta watch some of them real close.
anyway, what do you guys think of these? I have no damn clue, do they make this paint in braille?

Hey guys and fish,
Looking at the Yukon manual that guppy sent I think I might be just a tad too close with the pinion. Page 17 shows what too close patterns look like and page 15 on the right hand side, middle pattern looks pretty close to mine as far as I can tell. . .but what the hell, why cant they just show actual paint instead of "artists renditions?"
All that said, I do not have a lot of options in shims. If I drop back down 0.0025" (yup, that's a small increment my friends) then the pattern is clearly too deep. So what is the thing to do, accept it as close enough and let it eat, lap the shims, go buy some magic shim assortment?
If only there was some way that I could get someone that knows what boudain is to weigh in. A pincher of tails and sucker of heads perhaps? I mean, Giordano's has weighed in from Goose Island already so I need someone with access to good andouille. Yeah, I live in a food desert. . .
