I have an 05 Dodge Ram Quad Cab Hemi that only has 19,xxx miles on it. I had the output transmission shaft seal replaced about 9 months ago because it was leaking. Then it started leaking again, so I had it replaced again last week. Now it is still leaking. The dodge dealership says that they think that the yoke is bad and that's what's eating up the seal. Can anyone explain this better to me, and why didn't they see this when they fixed it last week, and how does this happen? Any help or advice would be greatly appreciated!
