Dana 60 ring and pinion

I am not seeing any pattern on the ring gear. Put some pressure against the ring gear when checking the pattern. Looks like it might be a mismatched gear set.

They are a matched set. Just used and I'm not sure how they were installed before.

Looks to me like you don't have enough pinion shim. Have you tried quiet a bit more than what you currently have? I would try at least .015 more and see what it looks like.

Got it figured out. Thank you

what did you do?

Use this thickness chart if you do not have access to the old shim or the old gear was not set up correctly.
I also use this chart to start over when I'm having trouble getting a pattern.

ALL DANA'S .035

Instead of honing the bearings polish the ends of the spool and the pinion with wet/dry paper. I won't take much for the bearings to slide on without pressing them on.
