Anyone ever have an extremely hard time getting the pinion to get out of an axle housing? Pinion bearings on my wife's JKUR went bad and I'm trying to replace them but literally can not get the pinion out. Started with a punch on the end of the shaft, then decided to try the nut on the end of the shaft, then used a piece of brass, then said fawk it and just put the sledge hammer straight to the pinion. Still no dice. Going to try and borrow an air hammer in the morning but after that I'm out of ideas

Air hammer didnt touch it, and neither did a bigger sledge. Going to try heating up the bearing with an acetylene torch next

Stupid question but is the carrier removed?
Yes, and that was also a pain in the ass thanks to the stupid electrical connector going to the locker. Working in my cold barn and the plastic just cracked everywhere.

I also removed whatever plunger sensor that threads into the side of the pig

That happened to a buddy of mine recently. He had to remove the axle, heat up the pinion bearing and put it in a press to get it out. I would try the torch first. You might have to use the torch to cut the bearing off also. Good luck that sucks.

Would be a PITA, but I'd suspect it'll come lose on an H-frame press.

I had a broken axleshaft stuck in a spindle and had done all the same things as you did. I threw it on the shelf figuring if I ever needed it, I would figure out how to get it out.

After I got my press I decided to see if I could press the shaft out. Took longer to setup than to press out.

If I can't get it out with the torch unfortunately I'll probably put the wheel bearings back on, push it back outside and sit for a while. Which sucks cause it's my wife's DD but I'm supposed to have rough electrical done in our new house in 2 weeks and I haven't even started..

As stated previously get the torch out, we have some in the shop that just some heat helps loosen it. Then we've had others where we literally have to torch the bearing apart to get the pinion released. I know it goes without saying, but regardless with the torch/heat be careful and aware of the rest of the housing to try to prevent damage. Once you do get it out, pay close attention to how hard or easily the pinion bearing races come out for you also. If the bearing was bad enough to get that hot and weld itself to the pinion, there is always the chance of the race spinning in the housing.

If I find that the race has spun in the housing, the housing is junk right?

I have found a bare rubicon housing via Facebook marketplace..for $800...

What finally did the trick?
Got the bearing cherry red hot, 3 tries of heating it up a little more each time finally got it with a 3 pound sledge. My arms felt like dead weight this morning though.

I pounded the races out of the housing last night too and it took a good amount of force to get them out and I see no signs of them spinning either so I'm in the clear to put this housing back together. Just need to get a new gear set cause this pinion is absolutely trashed.
