I do not post much but I am a regular reader. I am grateful for all of the information on the site.
I have a 8.5 10 bolt that I put a 30 spline truck truetrac and 12 bolt moser axles. I changed the gears from stock to 4.10 and installed all the above with a great wear pattern. I reused the shim under the large pinion bearing. I never ran the gears because I and am now building an 80mm billet turbo lq4 4l80e combo.
I changed the gears to a more turbo friendly 3.42, and now the wear pattern looks off. It looks to my novice eye that the pinion is too high and needs a bigger shim. In all my lurking here and elsewhere the norm is the stock shim is reused and is usually fine. Can you please look at the pattern and tell me if I should add a shim? If so, how much would be a good guess?
