Zillionith Rear main seal question I'm sure.

[cityjack]

Another thought if I may. I really love my Jeep but tearing this thing down is starting to wear on my knees and my forehead can't take any more scars this month. Seeings how the front tranny seal was the culprit, what do you think about replacing that main front bearing while I'm right there? The front shaft does have some wobble in it. Not sure how much is too much. I know what a bad bearing feels like, Just not sure how much is too much. How hard is the bearing to replace?

Thanks guys.
