I did it last night on my back in my driveway, wasnt so bad but wasnt fun either. I set the e-brake and jacked the front of the truck up and supported the front wheels about an inch off the ground with jackstands under the frame rails. I then drained the diff and then I marked and removed the six 15mm bolts from the CV shaft and pushed the CV shaft out of the way, then I removed the for 15mm bolts for the skid plate, then I lossened the two 21mm bolts from the clutch fork shaft leaving them only on a few threads. Then I removed the wire for the 4WD actuator followed by removing the six 15mm bolts that hold the clutch fork tube to the diff. The only difficult part was getting the tube off. As I went to pull the tube out of the diff it wouldnt come far enough out to get it off. On the bottom of the diff is a eyelet for what i dont know. I tool a long screwdriver and placed it thru this hole and pulled down on it to angle the diff just enough to sucessfully remove the tube. Once out I inspected the inside of the diff to see there was the fork spring and a washer inside. I took them out along with the tube and brought it over to my work bench. I removed the snap ring and the flat washer and the tab washer and smacked the shaft out with a rubber dead blow. I then carefully pryed the seal out, wiped out the tube, inspected the bearing, oiled up the inside and outside of the new seal and tapped it in. I wiped down the shaft and put it back in. I placed the tabbed washer and flat washer on and installed the snap ring I took off. I referenced the exploded view of the shaft and stacked theclutch fork spring and washer. I wiped down the face of the flange that mates with the flange on the diff and applied a small bead of permatex. I carefully installed the shaft back in. It was hard to line everything up. I had to call my brother to pull down on the screwdriver I had ran thru the eyelet in the bottom of the diff in order for me to use two hands to coax the tube in. Once in I torqued down the six bolts and the nuts. I reinstalled the CV shaft to my allingnment mark and let the truck sit for about 3 hours for the permatex to cure. I topped off the diff with almost 2 quarts of 75w-90 synthetic oil and and drove the truck with the raidio off switching back and forth between 2WD and 4WD and everything checked out. I looked back under the truck for any leaks and none were present. For the $200 labor I would have paid a mechanic, next time I will pay a mechanic.
