I didn't see this disassembled, so I need some help for reassembly.
The grease baffle does not look like the illustrations in the manuals and parts catalogs. I cant figure out how it goes together, Here are the pictures.

I have shown both ways to mount it. Neither seems to fit, as it will not tighten down against the backing plate. Also, the bolts don't seem to be long enough to put cotter pins in the castle nuts.
Also. which way do the bolts go? castle nut against the backing plate or castle nits inside the grease baffle?

It definitely mounts like the top picture but could this baffle be for a rear wheel. Are the spacers for mounting the e-brake carrier against. It has been a while but that is my guess.
The truck is a 29 but it has been modified with a dually RE. I'm sure that these baffles came off the front, as we have been very careful to keep front wheel- back wheel-left-right-etc, separate.
maybe others can help with the ID of this strange grease baffle. It just doesn't want to go back together right anyway we try.
Did the grease baffle on the other side mount OK? If so, and if the baffle that is being difficult is identical to the other side, the top of the bolt holes may have curled in from previous tightening, just enough to prevent the bolts from going though the baffle.
The baffle bolt holes may need to be reamed or cleaned up.
If the baffle bolt holes do not align with the spindle, then the baffle is not the correct one and got mixedup at some point.
What year are the front backing plates??? Is that not the subject? The pictures are too small for my eyes. But, I think the backing plate is a '30/'31. Attached is a picture showing the grease baffle installed on a '30/'31 backing plate.

Well, of course we can't be sure about anything, because we haven't owned the vehicle its entire life.
The front hub assembly is definately a 4 bolt assembly. We know that. It does not look like the picture that Neil provided, as his is a 6 bolt assembly. The grease baffle has tube like shoulders around all 4 holes that are as high (or thick) as the baffle is thick. One surface of the baffle has an opening slightly smaller than the opening on the backing plate, so if we mount the baffle with that side toward the backing plate, it will not snug close to the backing plate and will not tighten snug against the backing plate. If we mount the baffle the other way, it will allow the backing plate and the sleeves on the baffle to mount snugly, and I believe that is the way it was mounted, so we will try that again.
Thanks.
Barney,
The grease baffle in the picture is for a 29 with 4 holes , the back plate is 30-31 as Neil said and has 6 holes , you must have mismatch parts or maybe you trying to install the larger brakes on a 29 axle ?.
Your other post with the grease retainer AA-1197 is for sure 29, so if this hub came off this axle as pictured when you took it apart you have the wrong backplate, if you end up not needing the grease retainers I will buy them from you.

This is probably not your answer. I'm sure the baffle locates with the sleeves outward and I am wondering if you missed putting some kind of spacer on the opp. side of the backing plate which would move the backing plate out a tad and allow the smaller ID hole of the baffle to fit over the taper. Don't know about the bolts that you say look to be to short to safety wire.
Well guys, I don't know what to say except this.
The hub is 4 bolt,
The backing plate is 4 hole,
The grease baffle is 4 hole.
We put it back together with the grease baffle smallest opening out, and everything went together. We have our fingers crossed that that is the right way.
Something else we discovered is that the Front Wheel Inner Dust Seal is larger than a replacement we had ordered, so we didn't replace it. (I had thought that there should be a felt washer that fit in that seal, but I'm told that is not true)
So we have a couple of Front Axle Inner Dust Seals still sitting on the bench unused. You just have to accept the fact that you are always going to have a few parts left over, aren't you?
Thanks for your help. The lesson to remember is that good pictures during dissassembly are worth their weight in gold when it comes time to put it all back together.
Barney,
Would you post a picture of the stub axle with the backing plate removed and then another picture just of the back plate , the backing plates look much deeper that my 29 plates, in addition a picture of the brake drums that you took off or intend to refit .
