    Going through this right now to replace the seals. Passenger side came right off, no issues. Drivers side brake drum is seized on. Have a wheel puller, slide hammer, and cannot get this brake drum to give. Last effort will be to cut the brake drum off and replace. Hoping someone else has run into this before and knows a trick. Thanks, 68' CJ5 V6.

    Will the drum rotate?

    At first it did not, but I found the release for the brakes from the back. Got the brakes released and the drum does not turn.

    Which rear axle ?
    If it's tapered axle, you'll need a puller; drum is swaged to the hub.

    ...do you have a flanged axle in your 68 ?

    I have the original Dana 44 rear axle with the offset diff. Not sure if it is tapered or not.

    ok - if it has that big nut on the end, its a tapered axle. You are gonna need the big hub puller...and a lot of swearing....

    Have a hub puller from Advance on there now. Nut is off and have cranked as much as we can with a breaker bar. As yes, plenty of swearing along the way. Picture of the puller on the hub.

    looks like a hex head drive screw? Some of the big pullers have handles that you can bang on with bfh. Keep working it tighter and tighter, hitting the hex head on the end while you are tightening with the breaker bar, adding heat etc...letting it sit overnight....be careful, when it releases it can come flying off so don't stand directly in front of it.

    Yes, we switched to the Grade 8 hex head bolt as the one that came with the puller stripped out. We will try again with some heat and see what we can do. Thanks for the help

    PUT THE NUT BACK ON BEFORE MOVING FORWARD!

    If that hub flies off it could knock you across the garage. I think the only way you're going to have success is using an impact gun on that bolt.

    You might be better off sourcing the appropriate Hub puller.

    Read this post...

    Something Just Broke

    This is the puller you should be using. You take the biggest hammer you can handle and whack each end of the dog bone looking handle. It will seem as if you are going to break the puller, but you just keep smacking it with a hammer. The nut should be on just enough to prevent the hub from launching across the garage.

    Thanks as always guys. Started with the rear axle figuring it would be the easier of the two. I will get a different hub puller ordered. All the parts shops carry the same loaner tool.

    Apparently the tapered axles are a total PITA when taking them apart but is there any way to mitigate the struggle in the future?

    Is it a lack of lubrication?
    Corrosion?
    Dirt or filth?
    Or is dis-assembly with lots of harsh language just the nature of the beast?

    I was never exactly certain what I had (still a newb) until you mentioned that one feature. Thanks. (y)

    UM...... I may be wrong , but I was told to never use a torch for heating an axle. o_O Soak the bejeebers out of it.... Tranny fluid & kerosene or Liquid Wrench.

    Heat the brake drum, not the axle. Heating the brake drum will expand the metal and if there is rust may break the bond. Just take a propane torch and heat it for a few minutes and try it. Do it a few times and see what happens.

    My understanding - this is simply a feature of tapered axles. The taper wedges very tightly, and it's a big nut with a big torque value. You kinda want that kind of bond between the hub and the axle in service... Makes you wonder what enabled the switch to one-piece forged axles and flanges in that era.

    The new puller you recommended Focker worked perfectly. Just needed a little love tap from the BFH and popped. Now to continue with the seals. Nothing like a day project turning into a two week project. Thanks as always guys.
