You can get a rebuilt "housing" and new carrier bearing from Lowell Howe. He has this part remanufactured and sells an excellent product. No matter which is bad I would go ahead and replace both. Getting this puppy out isn't really complicated but I am quite sure I learned a few new cuss words during the process. Make sure you mark the drive shaft as you take it apart. You want to put everything back exactly as it was! If you get things out of alignment on the drive shaft you will develop vibration problems. Steve B.
