Ever since I changed my rear tire a couple weeks ago, I've noticed that my rear tire has been a little wobbly. After looking at it, talking to OAD, and then having a mechanic look at it, it seems that the rear hub is loose. I took it apart again tonight to take some pictures. Does this look like everything's right?

whats the conical spacer look like?

do you have up and down play in the shaft like a bearings going bad?

look and inspect all the other parts to see what the shaft was wearing against and if you can see any other wear some place else as well.

Take a couple more pics , maybe just a tad futher out and some of the other parts too.

The spacer looks OK, as far as I can tell.

No, the shaft doesn't move up and down.

The only thing I can guess for wearing would be the hub rubbing against the splines on the axle. But, like I said, I don't know. Maybe it's right the way it is...

I'll see what I've got for other pics...

First thing I see, use a little more grease when you put that back together, that shouldn't be rusting like it is. Looks like it went back together dry to me.

Can you pull the wheel of so we can get a view of the splines on the shaft?

The last time I had it apart before just a couple weeks ago was when OAD and I changed the rear tire last May. I don't remember if we lubed anything on the rear shaft or not. Do you, OAD? I don't think we took off the rear hub anyway, did we? Anyway, as I put it back together, I put some anti-seize on everything, which is the silver you're seeing on the shaft.

That was as much as I could see of the shaft. I don't know how to take the rear hub off, but I believe it involves taking off the brake calipers, and I'm not sure I'd feel confident of my abilities enough to do that. Those pictures are with the wheel off.

Ok, that is the hub I am seeing.

Put some grease on the back of the beveled spacer too.
What does the hub side of the beveled spacer look like?

That is a lot of rust on that shaft. Man I am glad I don't live in the rust belt.

I did put some junk on the back of the spacer. And it looked OK, once I cleaned it off when I changed tires.

There isn't a spacer behind the wheel that should be in front is there?

I'm pretty sure we did put some grease on the shaft and spacer. Believe I used the white lithium.

I was wondering something along the same lines, too.

Here's what I have on the shaft when I reassembled:

Tire (attached to hub)
Cone-shaped spacer - appx 1.5 inches
Swing arm (which isn't really a swing arm, but that's what I think they called it in the shop manual...)
Plain spacer - appx 0.5 inches
Axle nut
Nut cover
Cotter pin

Is there anything missing from this list?

not that I can think of. I just talked to Fuzzy and trying to brain storm some. Check your bearing in the swingarm, that could be causing the grooves we are seeing on the shaft.

I'm not going to take a wheel off just to look, but seems like a lot of spline inside the hub past the axle spline. Could the hub have moved on the axle?

When my rear tire was pulled, the small spacer was placed on the wrong side. Did the same thing as yours. It took about 2 weeks before the damage became apparent. The guy that fixed it at the vespa shop said it was easy to place em wrong. He had to fix quite a few of them. Said he had done one himself one time. I've decided to take pictures when I pull a tire on the rear of my 500 to be sure.

White lithium is not the right kind of grease to use on that application, you want something that will resist water. White lithium will just wash away with water.
I use Copper Coat or a little grease out of the grease gun (Marine Bearing Grease)

OK, I took my rear tire off again to make sure my tires were balanced. We'll see if that makes any difference.

Anyway, I took a couple pics while it was disassembled again.


Rear axle - zoomed out further.


Here's the 4 things that I have that I took off of the rear axle. (Well, ignoring the big clamp/swing arm/whatever it's called)

So, what I've been doing is putting them on in this order:

Taperd spacer -> big clamp -> small spacer -> 24mm nut -> Nut cover

Is there supposed to be anything else?

tapered spacer, then the wheel, then the swing arm, small spacer, then the nut. torque to spec and check for free spin so as its not binding. lastly install the nut retainer clip and a new cotter pin.

the axel pic is the wrong angle to see anything

Oh, the WHEEL! I knew I was forgetting something!

So, not missing any parts, then, right?

OK. Next time it's off, I'll see if I can get a more zoomed out from the back, too. But I'm really hoping I don't need to take it apart again before the Gathering. Maybe I will to put on my brand new tire (that I already had to get 2 pinholes repaired on ), but we'll see...
