With the pinion removed from the housing, press the old rear bearing off the pinion. Keep the shim behind this bearing for use later in this install. Use a pry bar to pull the old pinion seal out of the housing and remove the oil slinger (looks like a large thin washer). The front pinion bearing will also fall out of the housing at this point.

Pinion bearing 99 is correct. The bearing should be interference fit, with more interference expected on a pinion. Be sure to use a soft face hammer to press the gear out each time. I usually thread the pinion nut on until it is flush with the threaded end of the gear to help insure the threads will not be damaged.
