Well I'm finally doing this swap. Was waiting for cash but got forced into doing it now. My brakes went so I went in to put some spare pads I had on until I can afford a full rebuild on the donor axles. Upon pulling the wheel I noticed the ball joints were basically barely holding on. I could move the wheel about and inch in and out. Hahaha. Wondered what that clunk was. So, force to rebuild the donor and put it on. Now my questions.

First, I read a thread about greasing the needle bearings in the hub threw the abs sensor whole. Mine were ok and apart, so not needed, I will grease. But in the procedure thread it shows how to rebuild. It quotes a large yellow "O" ring that rarely leaks causing lock up failure. Both my donor, nor my original axles have no yellow O ring, and I cant see were it would go???

Second, There is a plastic washer in the hub that has 4 grooves in it. Manual says that lets the vacuum pass threw to lock the hubs. The donor only has one on the drivers side, not on the passenger??? I'm swapping some parts from mine so have the drivers off, and it has the washer, but I haven't pulled the passenger yet to see if ones there. Is there one on both sides?

Third. I know I will need to do an Alignment when all done, but. Upon buffing up and painting the donor. I have to swap the outer hub piece , from ball joints out, from my truck to the donor. That's why I pulled it first. The donor was in an accident and the arm for the steering is snapped off. I notice that were the ball joints go threw there is a bushing on the top one. It has some code numbers on them, and all are different, donor and mine. So four different bushings. Should I take the bushings from my drivers side, and put them in the donor with the outer axle, so they match? Or does it matter if I just leave the donor one in there and put my outer hub on? Not sure if they are matched at factory or not since they are all different numbers?

Sorry for the novel, thanks ahead of time.

 

The alignment shop will correct the camber with differing bushing in the top ball joint.

 

The needle bearing is only greasable by removing the hub assembly. It's what the stub shaft rides in, on the inboard side of the hub unit.

The big yellow o-ring goes on the hub unit where it seats into the steering knuckle. I've gotten these from the dealer before. Part number is F81Z-4A322-AA. If yours has been in there a while, it may not be recognizable as yellow . . .



Yes, there should be two metal and one plastic, in a sandwich. They are available as a set from the dealer. Part number is F81Z-3B458-AA.

 

Duplicate deleted . . .

 

I could be wrong but I think he may be referring to the large thrust washer that sits between the hub unit and the knuckle seal with the four grooves on it. Absolute, if that is what your talking about it should be on both sides and the grooves face in (away from the hub) on re-installation.

 

This is what he was referring to, and yes needs to be on both sides.




Not these, right?

 

Yup that's the one. Ok, got it almost figured out. 1000 bucks in axle u joints, pinion seal and bearing and race, and ball joints , fluid etc. BUT!!!! I can't find one of the seals. Upon pulling the front shafts I noticed one of the 3 seals is toast on both, and its the one no one has heard of or can find. HELP!!!! Both shafts have 3 seals. Starting at the pumpkin, there is one expensive one right there, then there is the giant outer one on the outside of the U joint on the Hub side. The one I can't find is the middle one. The one behind the u joint on the outer end of the shaft. It rides on a flat race right behind the yoke on the shaft, its rubber with a steel inner, and there is a plastic ring with it that's just floating around. Probably broken, but its worn and the metal is showing threw. I think its just a dust seal as no oil should get there, and it fits pretty loose in the tube. Any way, I want to put new ones on and no one knows the part number, nor can they find it on a blow up of the axle. Ford even gave me the inner ones. Napa too. Does anyone have that part number, or a supplier. Its a 04 dually 4x4 that I'm putting on my 02. Also its a Dana. Cant re assemble until I find this part.

 

The one on top of the green box goes on the axle tube. Is that what you are looking for. Sorry I don't have a better pic.

 

Not this one but the on that goes on the axle tube...

 

Now, I don't know if there is a difference between SRW or DRW. This shoes for a Dana 50. I will keep looking.

Ya the ones on the green box looks like them. Mine are worn into two pieces. Lol. The inner ones can only be done with the pumpkin out and are metal mostly. Totally different. Do you have that part number? No one can find it.

 

I also found this one for a 1 ton. Again I'm not sure if there is a difference between DRW and SRW. Part numbers are in the link.

Seal NOS 15553 | NAPA Auto Parts


Part # NOS 15553 looks like for the 1 ton
Part # NOS 21918 looks like for the 3/4 ton

Again not sure, might be worth a call.

 

Ok, that was the part number. Boy was mine worn out. These are one piece still. LOL. You americans sure get good prices too. THese were 26 bucks each. 18 for you. Ok, now for assembly. I have one more question. I got a new pinion seal and bearing and race. All looks good, except the new seal looks different. Size seems right inside and out, but its in two pieces instead of one?????? It has the main metal seal that pounds into the housing, but there is another rubber piece that looks like a compression seal or something. Its a rubber washer that has cone lip on it that appears is supposed to press up agains something to seal it. It is soft though, so wouldn't be tight. ITs obvious it slides over the shaft, but is it before the seal or after the seal behind the yoke? Never seen a two piece. THe rear is one piece.

 

Oh darn. I went and got the first one you posted before you posted the other. So looks Like I bought the 3/4 ton ones. Sure fits good. Wonder if they are the same?? THat said, mine were destroyed, so I'm alittle unsure of the orientation of that seal. It appears the plastic piece on the inside should face inward since it slides onto the shaft race nicely that way, then the large ring portion compresses when you push in the shaft. The other way I would have to compress the seal to get it on the shaft race, and then it would stay compressed since it would hit the yoke. So I figure it must be plastic ring facing inward away from the wheel??? I'm not a retard, its not even in the manual, hence my difficulty finding it. Hope the one ton ones are the same. On edit, I looked up the 1 ton seal and its the inner one they sold me by mistake. So your first number is correct, all I need is confirmation on the orientation. Thanks a lot guys. This is my first axle swap and full rebuild. Going pretty good so far. Looks brand new.

 

Thanks for the seal info. Sure some nice new parts you got there. Those rotors are nice. We can't buy those up here in Canada. Wanted to put some of those and the yellow stuff pads on my new set up, but not available in Canada. Boo hoo. Hoping our dollar improves so I can order some from Riffraff. Nice stuff, thanks again.
