front pinion bearing removal
The front pinion bearing on the rear axle of my 94 4cly pickup doesn't seem to want to budge. The inner race doesn't give very much area to grab onto so I didn't think it should take alot to get it to move but this one is being very stubborn. Any ideas or helpful hints? Thanks

They're meant to be hammered out with a drift pin. That's the only way I've ever done it. Piece o' cake...
See page SA-140.

There's a couple of notches on both sides of the housing behind where the races sit. Put the drift pin in the notch and bang one time on each side back and forth to push it out evenly. You'll see what I'm talking about...

As the manual describes in removal of the front bearing they use a SST09556-30010 to grab the inner race and pull the bearing out. That's where my problem starts. I've made a tool similar to the SST but it continues to slip off before the bearing moves. It's like the bearing is stuck to the pinion shat. Can that happen if the pinion nut has been overtightened?

Oh, I thought you meant the race. You mean the bearing. Well, that's obviously impossible, as you can tell. Hell, I wouldn't have even wasted my time trying it. There's other ways in can be done.
Hint: Remove the pinion from the bearing. Not the bearing from the pinion.
Like this for instance...

Thanks for the video, I guess a press might save a few hammers. That answers what should have been my original question. It sounded from other posts like people were replacing the bearing spacer or solid spacer without completely removing the pinion shaft. Anyway thanks again I'll bite the bullet and pull it all down.

I'm a bit confused about the preload. FSM says to initially set the torque on the pinion by itself to 7.8-11.3 in/lbs for reused bearing. But it seems to have the same callout once the carrier is installed like during a seal replacement. Am I reading this correctly?
