6. Remove the caps that are open. (the ones that are not seated in the yoke).
All you need to do is pull on them and they slide right off.
7. Rest the yoke against something solid so that one of the two remaining caps are facing upward. You can use a rock on the trail or the back end of a vice in the garage.
8. Use snap ring pliers or needle nose to remove the snap ring that hold the cap in the yoke. Do this to both sides.
9. Place a 3/4" socket on one of the caps and hit the socket with the BFH. Make sure that the yoke is back on the solid object before you do this and that the other cap has room to move out of the opposite side of the yoke.
10. Keep hammering until the cap breaks through to the inside of the yoke.
This will force the opposite cap to move out of the yoke as well but not
11. Remove the cap that you just hammered on by twisting the U-Joint until the cap is easily pulled out from the inside of the yoke.
12. Move the U-Joint around some more and the U-joint should come completely out. The remaining cap is easily removed by either your fingers or a pair of pliers.
13. Clean the Yoke with carb or brake cleaner and check to make sure that the yoke is in decent shape. Be sure not to remove the mark you made earlier indicating where the zirk fitting is going to be placed when you install the new U-Joint.
14. Line up the new U-Joint so that it will fit in the yoke, making sure that the zirk fitting is in the proper place.
15. Remove the appropriate caps careful not to loose the needle bearings.
