basically move the ring gear in closer to the pinion to get the pattern a little deeper on the ring gear tooth, it seems to be pretty close to the edge. i may be wrong though as im still learning wipe patterns.

i was looking again and there does seem to be a line on the drive side where its not going to the edge of the tooth, just like the coast, except the coast is more defined. maybe you didnt load it as good on the drive side. set your backlash within spec and gives us some fresh pics...

Yeah my plan is to tighten up the backlash a little more and then put some new compound on the gears and see what the pattern looks like. I'm pretty sure I need to add just a touch thicker shim between the pinion support and housing. I just want to get this thing together. Appreciate the responses so far.
Are you applying any preload to the side adjusters when setting the backlash?

mikey,
I have the preloaders pretty tight when i'm checking the backlash but i'm not apply any load to the actualy preloaders themselves with like a clamp or bar or something. Also when doing the gear pattern check do you spin the pinion both ways?

Those patterns are a bit unclear. Put a little oil on the ring gear teeth and make sure you have carrier preload, rotate the ring gear back and forth 3 or 4 times then take more pics so we have a better picture of the contact pattern.

I put at a minimum,,, 75lb/ft of torque on the side adjusters. This preloads the caps so they won't spread/move apart under a hard launch and f*(K up your settings.
Also, you should be applying resistance to the ring gear while spinning the pinion when doing your pattern check. Sometimes people forget that part lol...
I've never actually had a pattern turn out like yours before, with the drive side so far out on the heel, and the coast side so far into the toe.
Mike
Heel to Toe makes no difference if the pattern is centered from face to flank or top to bottom. If the housing was machined high or low you will get the heel/toe combo like shown above. Make sure your backlash is out to .010" and button it up.
