Hello guys,

Please take a look below and let me know if you think this pattern is good to go.

Thanks!

When checking the tooth contact pattern, did you put a load on the ring gear as you rotated the pinion flange?

Hello,

I think it's more accurate to say I put a load on both the ring gear and the pinion nut, that is to say I put a wrench on a ring bolt and a ratchet on the pinion nut and worked them both ways. But yeah.

Also, I looked at the pattern closely and made a command decision that the pinion was too close to the ring gear. I removed the pinion and bearing and changed the shim from .0365 to .032, rechecked and adjusted everything, and got these new patterns: How do they look?

Pictures on your second post don't display for me. For me, the first pattern looked pretty good. It will be nearly impossible to achieve a "perfect" pattern.

On new gears, focus on the drive side. On used gears, focus on the coast side.
