I have been rebuilding the differential on my 26 this past week. I have followed the MTFCA book on rear axles and now have it all together. However I have a problem with it being too tight when I torque down the bolts on the housing. It is just a few thousands tight so I can't rotate the ring gear. If I loosen up the bolts, it rotates fine. Any clue where I have something incorrectly assembled that has made it too tight? Thanks for your help. Rand
Sounds to me like you need to remove a little material from the thrust washers?
I am not an expert! But I have set up a couple T rear ends.
Better advice will probably follow from more seasoned wrench spinners!
Rand, You didn't follow the book. You bolt the two housings together without a gasket and check to see if you can turn the ring gear . If not you remove a little material from the 2528 bronze thrust washer face on the drivers side until you can turn the ring gear with a little friction. Then when you add the gasket between the housings you will gain 0.003-0.004 thousands clearance.
Take a little more off the thrust washer. I set mine so they are snug to turn bolted together without the gasket. When the .005 gasket is added makes them about right.
OK, Thanks for all your responses. How is the best way to remove material from the thrust washers? Do I take off and equal amount from both right and left washers? Rand
Rand, if you have your gear mesh correct, the right hand side thrust washer is the one to work on. If you take some off the left washer, it will open up your gear mesh.
Hope this helps.

Alan, I just pulled apart the rear end again. I now understand you're comment on the gear mesh. Thanks, Rand
Opps I mean your comment instead of you're.
Rand, try putting an extra gasket in.
