I was thinking they were what I would call spider gears in the diffs. But that I would think would be like 3 small ones and 1 large one per diff?
 
Close?

Nice guess.
If it was a regular diff, there would be 2 spider and 2 side gears all at about a 45' gear cut.
 
 
 
This is a special application for the torson 1 diffs. It is similiar to a old Toyota diff.
 
This diff has 3 side gears and one centre gear per axle shaft. Model year up to including 98.
 
Once the BTM has been used a lot, the gears wear and will give a problem similiar to brake chatter.
 

I'm assuming that's not metal in the bottom of that diff? If so ouch!!

I've never seen that set up, learn something new everyday

Thats cool.


So what would be in my 2000? Did they go to normal spider gears?

99-01 have torson 2 , Again  , not your standard diff.
   
Please correct me if this is not the design

Interesting. May need to dive into one soon just to learn.doing a complete front brake job this weekend. May have to open that up and clean up and re lube.
