Need tips on getting an axle out

Ok so im changing out the rear drum brakes of my gf's 1984 honda nighthawk 550SC.

Got the brake adjuster off, the torque bar thingie off. and the axle nut on the other side off (needed the breaker bar for that one). now I got the axle rod to pull out (its a shaft) of the right side. The right side bolt has a hole cut through it where you are supposed to side a bar or whatever and tug the rod out.

The thing is that this aint happening. I went to the other side and banged on the bar with a hammer (piece of wood in between) and split the wood. The bar didnt budge.

Today I'm going to get a deadblow hammer and try at it again. I'm wonder if you guys have any ideas on how to get a stubborn axle out? wish i had a pic but it basically bolts from the Final Drive side and you pull it out from the rear brake side (right).

Likely it's all galled and corroded because it's been on there for years. Soak it good in a penetrating oil like PB Blaster overnight and when you get ready to go for getting it out use a drift or a long bolt about 1/2 the axel size in diameter to rap it through. You may have to rap some and soak it a few times before you get it completely out. That's how I've done it and it took work and effort but I got it out. Clean everything up with a fine wire brush and wheel and I would recommend replacing the bearings and seals. When re-assembling use a good coating of an anti seize compound.
I'm sure others will have ideas and methods that worked for them as well.
Personally, I'd be very reluctant to use heat because it could be very damaging.
Good luck.

Wiggle the wheel while you are trying to hammer the axle out.

If it is that difficult, you may have a bent axle. OR, with rear tire off of the ground, wiggle wheel a little side to side. Axle might be binding up alittle, since it wants to come out straight and the wheel might be crooked. Can you fit a socket wrench extension into the axle hole on the left side to be able to tap the axle farther out on the right side? if you needed a breaker bar to loosen the axle nut, either you are 8 yrs old, or it was WAY WAY WAY to tight, which I am sure it was. Cant imagine it is supposed to be much more than 70ftlbs, if even that much.

And dont use heat, unless you plan on replacing the rubber seals in the hub of the wheel not to mention the seals in the final drive (shaft drive, I think). Too much heat will also deform the bearings.

Thanks for the tips... I'm at work now but will try some penetrating oil tonight... I dont think that wheel has been off for years.

The axle nut made an unpleasing "creak" when i was loosening it but came off with little fuss. The threads were a bit corroded but otherwise fine.

the Clymers recommended using a punch or drift to bang the rod out using a hammer. I have a feeling that lack of servicing has done a number on the rod, but it still spins pretty freely, so im thinking that it's just dried up in there.

Edit:

To give you an idea of how hard its stuck in there I put a long screwdriver through the axle hole on the right side, grabbed both ends, braced my feet on the tire and pulled.... nothing (its on the center-stand)

This is bananas, makes my BMW maintenance a walk in the park.

When youre too the point of putting the wheel and axle back on, finger in a good amount of bearing grease/lube inside the hub and work it into the bearings as best you can. If it is shaft drive, it probably wouldnt hurt to change out the 80w gear oil in the the rear end as well.

Bearings probably need to be changed as well... sigh
