Thanks a ton mdavidson, without your video I would have been lost. You helped me figure what guards to take off and how to pull back the differential to help get the old shaft out. I had ordered the new U joints and watched your video. But then on a tip from my brother who had issues with the process of pressing out the old u joint and getting the new ones in (and aligned) he asked me to check on the price of a new complete drive shaft. Turns out the U joints are about $20 and the new shaft with 2 new ball joints was $40-$50. I chose the $50 option as it was closer and it arrived in 3 days!
The new shaft is clearly built better, more beefy than the stock one. However when I greased one of the new grease zerks, the end of the zerk popped off. I can hand thread it back in the housing but when you tighten a bit more the threads pop loose. Bummer, bad zerk? I have it full of grease and hand tight but the next time I try to add grease I'm going to be in trouble.
It was a bit of a struggle getting the old shaft out since the 15mm bolt in the back was fighting me the whole way out and there is no room to get anything but a open ended wrench in there and make tiny turns.
Then, I think I did a very big bone headed thing. The new rear drive shaft came with 2 metal 'sleeves' in the package. I could not immediately see where they mounted or what they were for. When I had everything back together and guards back on, wheels back on etc, I looked more carefully at the old shaft and see that the old shaft has these 2 metal sleeves one over each end of the splines. I can see a shiny ring in the black steel where it appears something was riding on the sleeve, actually 2 shiny rings. Does a bearing or something ride on the outside of that sleeve?
I'm kicking myself for not studying that more carefully, and since this is the first time at doing a project like this it figures I would screw the one thing up that would require me to take the whole thing back out and start over to do again.
So what are those metal sleeves for? If they go over the splines, why did the factory not put them on in the first place?
How do you install those do you hammer them down over the splines?
Can I add them while the shaft is in place and just slide the front side out of the front of the motor, add the metal cover, then pull the back out of the differential and add the shield over the splines? Maybe by the time I have that all apart I might as well take the new drive shaft completely out and work on a bench.
Is there a way to repair the threads or find a new 45 degree angle grease zerk and try to fix that while the shaft is on the bench?
Many thanks to you who are chuckling at my rookie skills and are so willing to help!
