Is it a remedy for excessive ring gear run out (0.005 [measured 70,000 miles ago] when the specified max. is 0.0028) by replacing original side bearings with 266,000 miles on them, but never abused in any way, with new bearings?

Can you say what causes ring gear runout?
Is there any way to fix ring gear runout other than replacing the parts?
Thanks, but in this case the install was done by toyota and after 195,000 miles I'm thinking wear and tear somewhere, I was thinking maybe the side bearings.Bad installation can cause it. I had a 7.5 IFS ring gear "bent" by a poor installer back in the 90's
Thanks, I have just emailed ZUK. And yes, I guess refresh is a good way of putting it.I would think ring gear runout is the part itself or the carrier it is mounted to? What are you doing, refreshing a high mileage diff?
If it all looks good and ran that long already without unusual wear, I don't think it's an issue worth buying expensive parts for. JMHO
