[R-390] Differential Gear Assembly

[David P. Goncalves]

Hello all, 

 After disassembling the differential gear assembly and cleaning it, 
I put it back together with a smile of accomplishment. Unfortunatly, 
the bastar* binds up now. I did some reading on this in the Pearls, 
and it seems that the differential assembly has a particular assembly order.
Oops, I didn't note that. Now that makes it 18 different ways to assemble it.

Question: Why does it have a preferred assembly order? Why must a gear go onto a
particular shaft? Will it ever work again?

Observations: When it binds, it is a soft bind; it can turn through it, but with
some force. The rear steel gear is obviously not parallel to the brass detent
plate. One of the small planetary split gears has a noticable gap in the split
gears - the worst binding occurs then this gap runs into the sun gear. Oddly,
one of the planetary gear shafts is loose.
