Well,
I finally got around to fixing this today. I also regreased my slip joint as well. I had a few hiccups and thought i would explain.
I used this
Slip joint regreasing as a reference.
My first problem was removing the 4 drive shaft bolts at the rearend. They were very tight. I should have sprayed them with penetraing lube, but thought they may be somewhat loose since my ujoints were just replaced 6 months ago. Wrong! Also, the bolts are 12mm. The writeup has them a 8mm. I soon realized i did not have a 12mm 12 point socket. I am still building my tool collection, so off to lowes i went. I had sprayed the bolts before i left. I would also recommend using a pivot head breaker bar. A 1/2 inch drive head is too large to to work with in this area. They were easy to remove once i had the right tools.
Here is what the splines looked like after wiping them down. I was happy to see they looked alot better than the ones in the tech writeup. Not bad for over 200K.
Here is another. Looks like it could have used some grease.
Then i came to another problem. When i slipped it back on and went to mate it back up to the rearend, i could not get it to match up to the bolt holes. I marked everything like suggested. It took me a few minutes, and the i realized that the bricks i was using for wheel chocks were not pushed up under the front tire like i thought. there was about 2 inches that the truck had rolled, which in turn, turned the rearend piece that the driveshaft was not mating up with. I rocked the truck back a few times, and rechocked it. So, when you chock you vehicle, do it tight for this fix!
Thanks for the help everyone. Another cheap fix and more money in my pocket and not in some mechanics.
