mr T - with the links i gave you and if you are some what mechanicly inclined you should be able to do it your self , if you have never had one apart,and if truck hasn't been apart recently i would think you should be able to do it in 1/2 a day.you should not have to change the seal if it is not leaking, on the drivers side the seal is next to the diff..to change the seal the diff would have to come out.

 

here is another thread on the seal and leak https://www.dieseltruckresource.com/...threadid=65460

I think the center support bearing referred to is on the rear drive shaft...about center of the shaft.
