Yes, there are two yokes.
No, it is not difficult.
Yes, you can do it yourself.
Before replacing either yoke you need to get under the truck and grab ahold of your drive shafts right at the U-joints. Try to move them back and fourth, you are checking for any play at all. If you have play in the joints you will need to replace the joint itself.
Where your driveshafts enter your Tcase is where it can be difficult to feel for play. You want to do the same thing with the shaft. However, this time you will be grabbing the yoke and moving IT back and fourth. If it wiggles you have a worn bushing inside the transfer case. This can be caused from a poor U-joint as the rotation of your driveshaft(s) would not be a perfect circular rotation, I suppose it would be oblong.
I'm not mechanic, just throwing it out there.
Anyone support this?
