I spent about an hour disassembling (2) TOBs today; one 2013-2016 and one 2017+. Figured we would make some use out of it and share some photos and descriptions of the two since Toyobaru updated the part in 2017 and issued a TSB regarding it.
Below are some pictures along the way with what I found; along with some research I did regarding the PNs and bearing manufacturer.
The 2013-2016 bearing is from our shop BRZ, which had ~13k miles on it when we replaced the TOB during a clutch swap. The new bearing is from Subaru/Toyota, with the white dot notifying that it is indeed, an updated part.
Externally they look identical besides the white dot signifying 2017+.
Above is a photo of the non-sealed side of the bearing exposed. The PNs are identical between the two TOBs.
Here is a photo of the sealed side of the bearing once fully removed from the TOB. The PNs are identical once again (I will explain this below in further detail).
I then cut the two units apart to expose the inside of the bearing. Above is a photo I felt showed the difference in greases used well.
