i just got back from helping a friend fix their noisy civic
transmission. i gather this is a common failure and we replaced the
input bearing accordingly.
upon dissection, i found this:
the spalling is from high load, but i also suspect that the spacing of
the spalled regions has its origin in the original assembly of the
conrad bearing in the first place. there's nothing like a little
assembly brinelling to disrupt smooth rotation and cause high localized
short of boring out the housing and fitting a bigger one, i'm not sure
that's possible. i just replaced it with another honda bearing for
~$20. if it lasts another 200k miles with the wrong transmission oil
like the last one, i'll be happy.
