    Your pattern is REALLY hard to read but it looks way too deep. Are you putting resistance on the ring gear as you turn the pinion to take a pattern? Try thinning your paint with some gear oil, it will take a better pattern.

    Try removing .010" from the pinion shim and post up another picture.

    pinion is far too deep, take .010-.015" or so off the pinion and run the pattern again with about the same backlash.

    She likes it deep, but that is overdoing it.

    Its about 3/16 from the bottom. what do you look for???? How do you knock the bearing race and oil slinger and shims out without bending the shims????? all out of shims. I'll run it again with white and see what it looks like. I tryed yellow and added oil and stuck hammer handle by the ring gear for drag and you still can't see it very good.

    NO NO...

    Remove .012 for a start. Then when you get close add or remove in .002 increments.

    Too deep = remove shims

    Thats one of the pain in the ass things about regearing, not only of course constant shimming combos and rerunning patterns which is to be expected but with any dana axle is the issue of having to remove the bearing without damaging it. Thats why setup bearings are really nice, they simply slide on and off until you have the pattern where you want it. Then you can press on the real bearings and hope that the pattern comes out the same. They have some clamshell type removers that are supposed to not damage the bearing upon removal but I have heard they are not always full proof. Your on the right track just keep at it, it will pay off in the end. You want to pattern to be as centered as possible, it took me a couple tries until resident gear guru readymix helped me out. BTW, your gross ready, but ah well I had the same problem, I like to give it to em deep.

    Wow, I can't believe I wrote that.

    You (readymix) are very right, take ~.010" shims from your pack and see how it looks.

    My bad :doah:

    Look better but it still appears to be a little too deep.

    I'd say .002". You're pretty close with that last pattern :D

    Looks pretty damn good. I'd probably pull another .001 out and see if it looks better. By now you've gotta have the disassembly/reassembly down to 15 minutes or so....

    I could do it blind folded.:eek1: When I pull the pinion out the test bearing race falls out. The only thing is if there a big difference change when I put the new bearings and races in.
