ok the other day i finally got around to replacing the front and rear out seals on the transfer case. i also decided to install the KD transfer case upgrade for the pump. now no where did i read that this was to be a 6 hour job requiring 2 men and a small child. do GM engineers ever actually do any work on what they design???? So anyhow it went along quite well. was very glad to pull the T-case aprt as it was very dirty. magnet was full. cleanned it all up, all was ok. install of pump wear plate was a snap. hardest part was putting the case back together. got the special seal driver for the front seal. all buttuned up and installed. everying went back together nicely. took it out for a drive. all worked very well. used to leak out the seals some an i figured that i was getting some water in thru them as well when washed . now nice and clean, dry . pump wear clip showed no wear in it or the case. now just have to get and install a deep trans pan. hope that is a little easier....
