HI. I'm not sure if this is the right forum....built a Dana 60 rear diff. Pattern was good and b/l was 0.007" although I added a thin shim to the opposite ring gear side at the last moment so I don't recall whether the reading was as built or not. It has Motive gears which are known for noise and these are noisy on decel. I took the cover off after about 200 miles. The pattern looks ok maybe a bit towards the OD. B/l is now 0.012". Would you leave it or move shims? I think the pre load was a bit more than suggested using a rubber mallet. I can post some build pics and current pics.

Thanks. I think I will give that a go. I found a chart that says to swap 0.008" of shims to reduce the backlash by 0.006". I think I still have my dummy carrier bearings but I will need some new ones too.

Backlash spec for a Dana 60 is .006 to .010
I set mine to .006 trail rig only. if you drive it on the street .008 should be good and you won't over heat the gears

I must have screwed up somewhere. It was my first diff build. Wonder if I can save the bearings. It looks like you need one of those fancy clam shell pullers to do that.

It would make sense to have one of those pullers if you were going to do a lot of that type of work. I checked with one of the local shops and they don't have one.

After ordering bearings, shims and a gasket I got to it today and took the cover off again. I checked the backlash in a few spots and now I get 0.008" . The contact looks ok I think. I have no idea why I was getting 0.012" before. Even the tranny shift kit install went well this week. I guess a guy has to get a break once in a while.
