Looks like your pinion is too deep, rubbing the paint off the heal.

Also looks like the ring gear needs to be brought closer to the pinion, lash.

ive been chasing my tail all day and i can't find the sweet spot. in the pictures down below ive got .045 shims but it looks like it's too much still. the initial pictures were at .030. ive tried .035 and .040 with no better result. you have any suggestions to what i should try different? im at .008-.010 backlash
