Did you take pictures of the actual disassembling process?
I've got one pic of the inside of the wheel. I can post it if you like, but the disassembly was actually very straightforward. The reason why I was having trouble taking it apart before was because my Granturgismo shifter paddles were covering two screws. Once I removed the paddles and those screws, I had no problems. But here are the steps to disassemble it:
1. Flip the entire unit over
2. Unscrew the nut on the bottom of the gear shift lever
3. Remove all screws from the bottom of the case
4. Flip unit upright and pull top of case off along with the shifter
5. Remove all screws from the back of the wheel (There are 3 on the side spokes, 4 on the bottom spoke, and then 3 that attach it to the center of the wheel)
6. Gently pull faceplate off and unplug the wire cable
7. Remove the two black screws that hold on the silver DFGT name plate and all silver screws that hold on the motherboard
8. Gently pull motherboard from the faceplate
9. Remove all buttons except the red wheel (this seemed pretty stuck on there and I didn't want to pull harder and break it)
That's it. Very tedious, but pretty straightforward. After wrapping a few parts in carbon vinyl and putting it all back together, I just tested the wheel and everything works perfectly.
