Idk about the toyota dealers...this is places like amazon, or eBay that the seller claims they have a toyota parts outlet. The main thing is cost....people tend to look for a lower cost on what they assume is the same part.
If so, the new bearing will no longer have a press fit in the end of the crank. My guess...the old bearing would come out in pieces before that happened.
it may have grenaded on that input shaft?
from the pictures sent it looked rather roached on that tip and then wobbled the shaft the other input bearing had some wear
