Changing U-joints
I found several threads on this, but unfortunately none of them had pics. I'm changing the center U-joint on an 2001 extended cab 1500. I already have the back half of the driveshaft and the 4 snap rings removed. So basically I can use a BFH and socket or bolt and knock one cap through to knock the opposite cap out? Then repeat for the other 2 caps?

Yes you have to just pound the caps out of yokes. Do not hit the yoke where the snap rings sit or else you will have serious issues getting it back together.
First thing is that you MUST mark the 2 havles of the driveshaft and make sure that they are lined back up or you will have serious vibration issues.
Also try to hit the driveshaft near where the yoke is welded to shaft to prevent denting the shafts.
After the new joint is in be sure all 4 snap rings are fully seated.
Then "center" the joint by tapping on the yokes and be sure that it moves freely in all directions.

If they're the original ujoints then the caps will be glued in with an epoxy like substance and you will likely break the yokes, Your hammer or wear yourself out before they move. If you run into to this you'll need to melt the epoxy with a torch, it will be very stinky and smoky so use ventilation and be very careful to not over heat the driveshaft if its aluminum...if you have access to a ball joint/u joint press then that can make certain steps much easier...

Well I got it replaced. I tried the hammer method, but it barely budged after beating the sh** out of it for 5 minutes. I found my old screw type tie rod end puller, and it fit perfectly on all 4 sides. I know it isn't the right tool, but it did not even put up a fight at all so there was no chance of me bending anything. I might post a pic later if I can remember.
