Pinion bearing installed. I removed the old one with a Dremel tool and metal cut off wheel (or you can use an air cut off; I used E-Z lock wheels), a hammer and chisel. Also note the pinion shim thickness. Since I have changed gears I reused the old shim for a starting point. For this setup it was a 0.028" shim. Next I threw the pinion with shim into the freezer in the frig here at work (mini frig). Then I set the bearing up with a heat gun applied to the face side of the bearing (the point that makes contact with the shim on the pinion. After a hour in the freezer and roughly 5 mins under the heat gun the bearing dropped right into place. You could also do this with the carrier bearings and pinion races. However I used a brass & steel punches to knock those into place making sure they bottomed out.
