Rear axle inner spacer... Spacing?

I'm changing the rear bearings out in the 67 and have read quite a few topics here.
I made the bearing pull and have the bearings off, but read about clips falling out in the tranny.
My axle can pul out a hair, to the point where it's thicker area is about flush with the surface of the tube. Sorry for the craptacular terms but I don't know the exact words for them.

Pulled flush/to stop

Am I safe to proceed with reinstalling everything?
How far do I tap in the bearings? Just till the stop moving in?

Sorry, and thanks!

Put everything back on, torqued the castle nut to 210 (the max my torque wrench can go) and cranked it another quarter turn to line up the hole for the coder pin, then jacked the opposite tire off the ground and spun the hub I just worked on a dozen times.

No problems so I guess I did it right. Laughing

Looks right to me. There is a spacer, then a bearing, then a seal race. Looks like that will put you at the splines for the drum. I've got '67 axles on my buggy.

What prompted you to change the bearings? I think the only reason I've changed them is because I've pulled them.

Good for you they are pretty forgiving, but dang son don't be pullin' out on that axle too much! Shocked

That can get you in deeeep trouble with your fulcrum plates Laughing

Should the inner spacer be recessed in the axle tube or sit flush with the bearing surface?

Without the bearing on there yes it should be recessed. How much is a factor of your particular axles, tubes, side gears etc.

Keep in mind that the axle is pretty much "free floating" at the trans end where it fits with some play into the fulcrums/side gear/differential assembly.

At the outer end is the only place where the axle is positively located.
The combination of all the parts, including axle, spacers, wheel bearing, slinger washer, brake drum and finally a fully tightened castle nut make up a "hub" assembly that carries most of the loads.

So, should be nothing to worry about, once the bearing is driven fully on and seated by final compression it will pull the axle out a little to allow some needed clearance and end play at the trans end.
It's nothing that can be measured but perhaps only calculated by deduction?
Here is where knowing that the stack up of parts that makes up your "hub" assembly are all compatible and of good quality is most important.

I really appreciate the input. When I pulled everything off I noticed one of the washers was marred up so I am thinking my bad bearing hypothesis was correct.

I did notice on my left side an almost fibrous build up around the brake cylinder, and that one side was pushed out further than the other. Either they aren't adjusted correctly or it's going bad. Brick wall
