off my new to me "Jeep" trailer. It's a custom-built trailer that has reportedly been built to match a 1978 CJ5. In case that helps, I'm told the CJ had upgraded axles and that it is possible that this hub is off the original CJ axles, or was intended to match the CJ axles, but that really is conjectural.

it's 5 on 5.5". Studs are 1/2". The OD of the projecting cup is 3.355"

The bearings are something like (not sure, can't read very easily) : LM603049 for inner and LM501349 (inner ID is 1.625") for outer.

The hub is on a spindle that has journals of 1.621" and 1.777" OD. See pics below. Doesn't seem to be a standard trailer spindle from a quick search.

The seal is 2.5" ID and 3.25" OD.

So, any idea what this hub -and spindle- may be off originally?

The idea is to identify them and find out if I could get some hubs in 6x5.5" that would fit the spindle. (Unless you tell me that I could have it redrilled easily and cheaply enough). And yes, one could get adapters but those are not that cheap and would put the tire a bit too far out with the rims I have.

spindle pics

the spindles are on a 3.5" OD tube (don't know if it's a slip-in or just welded on).

Sure looks like a dana 44 hub and spindle , what did they use for the end of the hub like a dust cap ? should be a locking hub on end to engage 4x4 . hope this helps

yes, the hub just has a grease cap on the cup


a quick search on the bearings did show some broncos and also F150s with those.
did the CJ5 come with OEM 44s?

I do not think that they did, however some 1/2t GM trucks did and were 6 lug as were some of the Jeep full size Cherokees etc. A little scrounging of jeep parts should turn up some 6 lug hubs if that's your goal.

The QuadraTrac Jeeps as well as the GM trucks that had the full time 4WD (NP203 t/c) had drive slugs in the wheels hubs that were covered by a chrome cap that pops into the hub. Alternately you could put some Warn Locking hubs in there.

yes, I don't recall CJs ever came with 44s. They were D30 I think.
The fullsize Wags and Cherokees did have D44s though.

edited for new info:

Some more searching suggested that these spindles are Dana 44 "SMALL BEARINGS" spindles. Equivalent Dana p/n is likely the 706528X.

These were used on Wags, Cherokees and Chevy/GMC 1/2 tons, and Broncos, mostly in the 70s. (Which suggests that my hubs are Broncos then.) So maybe an early Chevy or Wag hub would fit the spindle and give me the Cruiser 6 bolt pattern. BUT, I also read that the old Cherokees and Wags that had the 6x5.5" pattern had a 108mm bore wheel. Which means that those hubs may well not fit the LC series 80 (106mm?) bore wheels that I was hoping to use. To be checked.
Seen it mentioned that the Chevy bores are mostly 78mm, which would be better. The studs, however, are mostly 14mm (or 1/2 - 7/16"), which is bigger than the 12mm on the 80 LC, so may not fit my 80 wheels.... Dang...

Making progress...

Your spindles aren't Ford as they are 6 hole. The Ford, or at least the Early Bronco for sure and I think all of the other Ford D44 spindles were 5 hole.

Unless they used the 1/2 ton Ford TTB spindle, which is 6 hole. They have a different offset so you cannot use them on a solid axle, but for this, since there are no brakes, I don't think it matters.

So e9999, find someone around you with small bearing chevy or small bearing full size jeep ( FSJ) hubs and try them out.

Oh yeah, to bad you haven't posted a picture of this mystery trailer yet....:p

The spindles I don't know for sure yet, what I wrote was that my hubs were probably Ford, given the 5 lugs. That seems to be also a common conversion to go to 5x5.5" on a Chevy or Wag spindle from what I've read.

One bit of good news is that my Tundra steelies have a 14mm stud hole, so the Chevy studs might work on those. OTOH, the center bore does look more like 106mm than 108mm so the Wag hubs may not work if they are truly 108. Need to check more carefully on that.

I did see that thread when researching this. My spindles do look more like the Ford ones, don't they?

Not so easy to borrow somebody's hub unfortunately, especially since I don't know anybody with that kind of truck. And buying used hubs online is a bit iffy.

Pics to come.

I have to say that the locking nut system on that spindle is pretty nifty.

If your worry is the hubs clearing your rims, depending on your relationship with your favorite parts store, they can order one up to see, and you can see if it will clear in the store. No cost.

With the price of scrap cleaning out the landscape, not sure if you would find one in the salvage yard or not. I haven't seen one in the last 6 months. I think the ones I had, I gave away and he sent them for weight. Most Jeep and Chevy guys upgrade to the big bearings if they have any problems with hub / spindle.

Standard Dana front style of spindle nuts, also found on the Chevy 10b front.

What did the wear pattern tires off of this trailer look like?

All this might be mute, if the yahoo that attached these spindles to that tube ended up giving you some unneeded camber or toe. You might end up replacing the axle anyway.

yes I'm hoping to find used ones to save on cost but may indeed need to go new.

Looks like Ford has some interesting ratcheting nuts.

Tires were replaced recently so can't tell.

I think the trailer is extremely well made. Was done by a pro shop. I'm betting that the spindles have been welded on just fine. And tire wear is not a major concern given the little mileage it will see anyway.
 
TTB doesn't count, regardless of the application they're weird anyway. :)

2mm would be short work for a die grinder and a carbide burr. You would loose the hub-centric feature if you ever put those wheels back on the Tundy, but I'm not convinced that this is a highly important thing unless the Tundy doesn't use conic wheel nuts in which case it's absolutely necessary.
