right front universal joint

[JoeGrapes]

On my '89 Jeep Cherokee Sport the right front universal joint is bad. I went to the parts store and got a new joint. It's a standered looking universal joint with 4 clips to hold it in place in the yoke. The joint on the front axle has what looks like metal caps on the ends of the universal joint. There is a lot of rust so I'm not sure what I'm looking at. What am I looking at? I'm no stranger to auto mechanics but I never did these before. After taking off the brake caliper and the rotor and the axle nut cotter pin and nut, will the axle shaft slide out so I can replace the universal on the bench? And how does the universal come off the yoke? I can't see where the clips go because of what looks like caps on the outside of the yoke. Any ideas would help me a great deal.
