Also How to tell if it is a tapered axle or non tapered. I understand the tapered need the puller? Would mine have a left over MB or something? It has a lot of the VEC features.

A service manual would help you determine that.

If it’s the early axle you’ll have hubs like the illustration and you shouldn’t need a puller. My mb manual says there are two holes in the axle flange that you can screw bolts into to pull the axle shaft, the cj axle is probably the same.

Also, in addition to the difference in hubs a CJ2A (Dana 41) axle has a round cover over the differential, the MB cover is nearly rectangular. 

If you have the Dana 41 it will be tapered axles and you will need a puller similar to the one below.

it's a Dana 41........will be very hard to buy a tool for one time use.
Thank you for that info. Very much appreciated from everyone.

Better see if you can borrow or rent one. Trying to pull a hub with anything else is sure to result in damaged/destroyed parts. Ask ANY of us how we know!

Damaged parts, and injuries. When you do find the appropriate puller you need to have the axle nut on a few threads to keep that massive hunk of iron from popping off and hurting you.

Also become familiar with how the hubs need to be reinstalled. I have lost count of the ruined hubs I have replaced on Jeeps because someone put the key in ahead of the hub and split the hub. Really simple, hub on first, align the keyway, tap in the key flush with the outside of the hub then the washer and nut will push both as a unit when the nut is tightened to spec. 

It is a tool that most people use infrequently, but they aren't overly expensive, and cheaper than replacing hubs that have been ruined using the wrong tools.

I will take your advice and also read up on it when I get to that task.

In the back of my design engineer's (Ret.) mind I have been thinking that the puller used by most is a "universal" one. It is designed for a lot of lug patterns. SOoooooo since I only need one lug pattern and a puller is not high tech, maybe I can make one. But it is $75 and $131 on Amazon. That makes it a hard choice. I will probably search my metal scrap pile and puller parts and think on it. I do have tools to make one.

Here is a homade jeep specific rear axle/hub separator that I designed.
Works fine but I used 1/4” which is a little weak so I suggest 5/16” or 3/8”.
It obviously uses lug nuts to separate so end cap distance to end of axle shaft is very important.

I have often thought about making one using one of the ruined rear hubs I have laying around. Would have to do some lathe work but I don't think it would be too difficult.

I think I would just use a square or rectangular plate 3/8-1/2 thk. Use a wheel or front drum for marking the pattern.... A center bolt from another puller....

Keep in mind I haven't scoped this out, just now thinking about it from inside my house because of this discussion.

The attachment to lugs is maybe a small challenge to make. possibly just use chain. loose or welded to make feet. I'll probably brainstorm this for weeks.

Where are you located in general terms? You never know, there might be one you could borrow locally.

My local NAPA has one that they "rent out" for free. You leave a deposit & use the tool. When you return the tool clean & in good shape you get the deposit back.

Many FLAPS have this option for rarely used tools. I have "rented" many tools from them, like a fuel pressure gauge for my wife's Buick, a torque multiplier, & a dial bore gauge, to name a few. Check if you have this option locally. It is much cheaper than buying one.

Where in the desert are you? If you are close to one of us, we might loan ours out to you.

Here’s a view of the other side.

Ken,

That is a brilliantly simple design. Until you showed the flip side I wasn't sure how it worked.

If I am understanding this correctly, this sits over the end of the axle with some space between the flange and hub and you just tighten the lug nuts to pull the hub.
