After looking at the differential some more, it looks like I'm going to have to take the rear wheels off, pull out each axle, and remove the bull gears.  Otherwise, the brake housings won't come out all the way.   Is this right?  I'm still hoping I can do one side at a time.

I got the brake housing shims out and moved the brake housing a little, but it's still pretty tight.  Any thoughts.

I hope none of you guys never have to replace the differential thrust bearings.  A lot of work for $40 worth of bearings.

Thanks for any comments.
