Narrow-track, open-knuckle Dana 30 front axle questions...

My machinist said my drums are done. I'll put up some photos when I fetch 'em.

 

Another question.....the big seal at the back of the spindle, what does that seal against? I was assuming it was the slinger on the little stubby axle that goes through the spindle and hub, but it's smaller than the seal ID.

And where can I get those slingers, and the slingers on the other axle shafts that go into the axle tubes? All of mine are shot, can I get those at a FLAPS? Dealership item only? 4x4 specialty shop? Or perhaps a driveline shop? I haven't had a chance to search for them yet, but need them like, next.... along with the bearings and seals for the spindle and hub.

 

I was just taking mine apart and noticed that big seal was crusted over like it wasn't touching anything.
Turns out that it is a good deal bigger than the OD of the outer axle stub.It has the same part# as the wheel seal. (8430S)

Design Flaw???

 

True statement.

This is a list of part numbers from Advance that I used (National Seal)

Wheel seal for drum setup (for spindle to axle...2.125x.0050x0.25): 8430S
Spindle hub seal (hub to spindle...(2" ID): 472397
Spindle small v-ring seal (inner rubber seal for spindle bearing...1.313x1.625x0.1560): 722108

From Auto Zone:
And the bearings (Timken)
Spindle bearing B2110
Wheel bearings & races SET45

From CompleteOffRoad.com or OconneJeep.com...I forget which:
Axle U-joint (Spicer) Non-greasable 5-260x
Spicer ball joint non-greasable 706116x

Oh yeah...you can get the slinger at 4WD.com

 

Man, that 4wd.com site is so complex and hard to figure out it makes me want to scream. I can't find nothing there! Says they've go over 300 drawings and diagrams.....where the hell do they hide them? Search for "grease slingers" and see what ya get, everything BUT grease slingers.

 

Search on "Dana 30"

It is a dust shield.

Thanks guys!!! OK, dust shields then. When you don't have a reference that names the parts, ya gotta guess. I still can't figure out how you found that page for the axle parts and drawing.

Now, there's two kinds of them, for the inner axles and the outer axles, and they're different sizes. See Lynn's drawing - #14 is an inner axle dust cover/shield, what's the outer axle dust cover/shield?

Is there not any seals in the ends of the housing tubes? What keeps funk from going past the dust cover and getting inside the tubes?

See diagram #11, the spindle seal. What does that seal against? See DREDnot's post #23 above, I don't understand WTH is supposed to go inside that seal. Is it the mysterious object right behind it with no diagram number? Is that the dust cover for the outer axle? If so, it's OD is smaller than the ID of the seal.

And where's the info for the hubs for this axle? Not the Warn locking hubs, the part that the wheel mounts to! I need the bearings, races, seals, nuts and lockwashers. Those aren't listed on this page.

I'm pulling my hair out here.

I see 4WD.com has a Denver store, guess I'll have to see them.

 

As far as I know you need #14...I don't know where the other is located.

It's only the dust shield. The other seals are located in the tubes close to the pumpkin.

I think that's a great idea. All you really need to give them is the year and type of axle and I'm sure they'll set you up. The only issue is that I'm not sure of the type/quality of parts they carry...be sure to ask for name brands if that's what you want (e.g. Timken bearings, etc.). My parts list a few posts back should give you something to go by.

 

OK, got some photos now. These are the outer axles, and the dust covers I need. Are these things supposed to fit inside the spindle seal? 'Cause these sure didn't fit in the old seals.





These are the inner axles, these dust covers are much smaller.



No seals in the ends of the tubes to keep crud out?



I assume this takes a special tool, and has to be torqued to a certain value, after the lower ball joint nut is torqued?

 

Thanks Lynn! I had a pro do the diff., so the tube seals are in place and done. I just don't understand why they didn't put any at the end of the tubes. And I'm still stressing about the seals on the spindles and WTH they seal against.

 

OK, I'm stupid. I was comparing the wrong seal to the outer dust shield. The seals from the back of the hubs and the spindle looked identical, but the ID's are a tad different. So, the dust shield does fit into the seal.

Went to the 4WD.com store/warehouse and got several of the parts I need, but the outer dust shields they have are larger, later model ones. And they didn't have the Timkens bearings for the hubs or the large seals for the hubs or spindles. Bearing supply house is next.

But I still need the outer dust shields for a '72-'75, anybody know where I can find 'em? I'm going to try Walck's in the morning.

I didn't even know about that 4WD.com store/warehouse here, helluva place! I'll have to remember that.

 

The trick to using the 4WD.com online catalog, is to go into the "Replacement Parts" area in the "Shop by Catagory" box.Then pick the catagory "Axle Parts" then scroll down to "Vintage Model 30 Axles"

Thats where you can get to all the diagrams and the click on the number of the part and it scrolls to that item on the list with the item you wanted on the tippy-top of that scroll.

Once you get the path down, there is a wealth of info on that site.

 

I'll have to check it out, thanks for the info! Even the guy at the sales counter grumbled about their website and how user-unfriendly it is.
