Rear axle question

[Stargazer]

Ok,

I pulled both axles of our 67 New Yorker. For inspection and freshening up.
Good thing I did, oil seals need to be replaced.
Pulling the right side axle however, a small part came along and fell to the floor when the axle came out.
I fear it is something which belongs in the differential. Looks like it was against the axle.
The service manual doesn´t show this piece.
Anyone know what this is? See pictures.

Also noticed there was way to much endplay. Perhaps that explains the scratches in the oil seal. Looks like the collar was rubbing against it.

Aha! Looks like the lock pin broke off. So the differential needs to be removed I presume?

Does this apply here?

How I Do It, Sure Grip Spacer Pin

"On cars with Sure Grip, pulling the axle almost always results in problems from the spacer pin."

Is this thrust spacer only seen on diffs with sure grip?

See also here (re-install axles and bearing without doing anything about the spacer):

Is this a thrust button and can it be removed?

Hi FABO. It's me again. Engine is in. Working on replacement of 7 1/4 with 8 3/4. Have a narrowed housing and axles with green bearings from Moser engineering. Comments came up regarding thrust button or thrust block removal. Research tells me the cone style sure grip, which I have, does...

Yes it does.
Since many advice staying with the original bearings (which look still look good), the differential will have to come out. I think replacing the pin is above my wrenching skills. And will ask a Moparshop if they will do this job for me.

I don't think it's going to be a big deal. If the other part of the spacer isn't still in the differential, I think you'll have to pull the carrier out to find it, but that's just some "bull work" because it's under the car, heavy and full of oil.

You do need that spacer to maintain your axle end play... So it needs to be done right. I'm not sure if that spacer will need to be replaced. I think it will depend on what condition the pieces are in. Replacements are cheap. "Powr-lok" Thrust Buttons

Now that I did some research online, it seems that a shop is not needed. Will indeed need to pull the carrier because the other spacer is nowhere to be seen in the other axle pipe. Probably somewhere in the housing. I figure that loose spacer could do some harm to the gears when left there.

Thanks for the advice, as always!

Still I wonder, why does the "locked with pin" spacer disconnect from that center piece?
And in my case follow the pulled axle. Sticks to it because of the thick diff oil?

 

[Stargazer]

Well pulled the diff (wow heavy MF), and found the lost thrust spacer on the bottom of the housing.
Now, how to get these spacers, or a replacement set (probably needed because of pin) back in place, without dissasembly of the whole differential?

I've had a couple friends that could just lay on their backs and pick the diff off the floor and slam it in place like it was nothing....

If you think that existing part is usable, what I would do is clean it up really well and then apply a little red Loctite on the pin and maybe a little grease on the flange of the spacer to hold in place. Then magnet on a stick to insert the halves. Once one is in, hold it in place while you stick the other one in.

Yes I think David Freiburger wrestled one in, in a episode. I used a Jack, my bad back doesn't allow me to do this stuff by hand anymore.

The magnet, stick, Loctite and grease might just work. I will give it a try John. Thanks!

I've done similar and made long tools to install the thrust buttons w/o pig removal. It can be done.
