Wear pattern rear setup

[big gear head]

There should be at least .025 shim under the pinion bearing. These rear ends usually have between .025 and .045 pinion shim and usually around .030 to .037 is normal. If you only have .006 then something is wrong. Did you install the bearing race yourself? Are there any shims under the bearing race? Did you check the numbers on the bearing and race when you installed them? Did you use a .001 feeler gauge to see if they are both fully seated?

Thanks for the reply, yes I installed the race. However, I first made a set of setup bearing out of new bearings same which came in the rebuild kit. Same thing so I know the race went all the way down, even when I installed the new bearing and race I checked it with feeler gauge it was fully seated. What I find funny is why does the old pinion also have no shims? I'm at a loss two days and can not find anything. Also the backlash is at 6

How bad do you think it will whine if I left it?
