MCI-9 Tag axle bag

[babell2]

Last week I aired up the bus and started looking for leaks.
  I found the Bag on the left tag axle leaking at what seemed to be between the bag and the top plate.
  Can this be disassembled and cleaned or resealed? Or am I into a bag replacement?

The rest of the bag seems to be in good condition I am curious on how a leak could have developed.

rust thru from years of damp and salt exposure. I have seen it on the bottom but personally have not experienced on top.   I replaced assembly hoping to never revisit the problem.  Bob
