Ring gear play on carrier

[eschaider]

It doesn't matter what type rear end you are working with, you do not want anything less than a tight fit between the ring gear and it's carrier. Anything but a tight fit will produce a runout while the rear end is operating and advanced gear tooth wear and noise.

Get the correct carrier for the ring and pinion you are using or get the correct ring and pinion for the carrier you are using. Do not mismatch them. If you do you will not be happy with the result.

The Dana ring gear should fit and work on the carrier. As you noted the only change should be the ring bolts, flange and some bearings.

Obviously, something is wrong. Maybe it is the wrong ring and pinion set.

I have tried to contact Motive gear for ring hole spec with no success.
Another ring manufacturer (Richmond gear) give me the Dana 44 ring hole diameter to be in the 5"563 to 5"564 so i came to the conclusion that, with a pilot spec in the 5"625 to 5"564 (Auburn spec) some carrier / ring pairs have tight fit while other could have a very very little play (remeasured to 0"0012 in my case).
I notice also that old ring has a different manufacturing process ie a different cut process of the teeths and that the centering hole is rectified : it could explain that old process could be more precise to obtain tight fit while new process has more variations.
In my case, if i sligthly oil the parts, the play is no more noticeable at all. I have bolt the ring on the carrier and verified the radial runout which is below Dana specifications so i guess the setup is ok. If i order another ring i guess i could have same "issue" so my goal is to mount ring with a little touch of loctite radially applied on the centering diameters (not on the mounting surface althought i remember to have read that some guys do it !).

That's what the word "tolerance" means.
You have a "low" carrier, and a "high" crownwheel.

In a perfect world, a 1/2 thou, would give a nice transition fit, almost clearance fit.

Your current combo with a smear of 140w oil, nip up the bolts, fit the hemisphere only, measure gear runout, get a happy zero, remove the hemisphere, torque up all the bolts, fit the pinion, check the crownwheel pattern etc.
