If you have a leak, wouldn't you expect to see fluid on the ground? Have you been adding fluid?
Since you didn't provide any symptoms, I'm going to guess you have no power assist and are blaming it on the pump. A more likely cause is a failure inside the rack and pinion assembly. Replacement takes about 20 minutes, but the truck must have an alignment performed afterward.
If you replace the pump with a rebuilt unit that doesn't have the pulley on it, you will need to transfer your old pulley. This involves a pulley puller and installer tool and possibly a special spacer. Look at how far the pulley hub is pressed onto the old pump shaft. If the hub is flush with the end of the shaft, no spacer is needed when installing the pulley on the new pump. If the hub sticks out from the end of the shaft, one of two different spacers are needed to properly set the depth when installing the pulley. This spacing is critical for proper belt alignment. Misalignment by as little as 1/16" can cause a belt squeal that is impossible to solve.
