Technical 9 inch axle seals

I think my galaxie is going to need a axle seal so there are two different sizes of seals,since its not a wagon or a truck with the big bearings I presume the smaller seal is what I need. I just do not want to tear the car apart and leave it in the driveway since the seals will have to be ordered and this is the time of the year the city starts snooping around and do not need them getting to nosey and I might need to get the cars out of the garage.

 

take the wheel off, remove the drum, pull the axle, read the number on the old seal or measure, put the axle back in, and order the parts. Then when the new seal comes in, you repeat the process, but it will be much faster since you'll have already got the wheel bearing loose in the housing (that's the challenging part of this whole project)

 

Its too damn cold again today to even want to mess with it,it was very nice friday but back down in the upper 30s again today. I just want to order the parts and take it apart once as I hate doing anything twice if I do not have to.

 

i have CR # 13738 written down for a small bearing 9" axle seal.....better double check that since i also have # 13700 written down for an 8" ford rear

 

I would have thought a 8 inch and small bearing 9 inch seals would be the same since the 28 spline 9 inch axles will fit some of the 9 inches and I think the bearings are the same.

 

In that situation i just order both seals because they are probably not too expensive. Easy to store and you dont lose time waiting or driving back and forth. I know its a waste but oh well. To me its that or tear it apart twice or leave it tore apart.

 

i kinda thought so too.....but looking at my notes i definitely have the two different part numbers.

 

Just installed axle seals in the large bearing 9 inch and there were two sizes based on the splines, 28 splines took one size and 31 splines took another. Obviously the splines don't make any difference as far as the seals go, but the axle diameter is different with the different spline count. So, you need to know the bearing diameter and the actual diameter of the axle shaft in the seal area (but I think the parts houses list them by spline count). I had a h***le figuring this all out!

 

I agree with squirrel, you are going to have to see what's in there unless you are positive that the rear end is the one that came with the car and you can look it up that way, otherwise there are just to many variables.

 

When in doubt order both. Then return wrong ones later.

I know it has a original rear end and it has the small bearings as I did have new bearings pressed on and I think i put new seals in it at the same time,I need to check the vent.

 

I just completed the same task. The correct seals for a Ford 9 inch small bearing with 28 splines is National 9569S which are available from NAPA for $12.50 each. The correct bearing is CW207-CCR and they cost around $40 each. Be sure to use a seal driver to install the seals. I hope it warms up for you guys. Your local dealer should have them in stock as they are used on many applications.

 

Typed in CR-13738 in the zones website and came back with 9568 and in stock

 

Autozone has 9569S seals in stock but their computer says no way for 65 galaxie,I think its time to buy some old parts books so I can get numbers.

 

This has been covered in this thread already. Buy both sizes and return the wrong one later, or take it apart and make sure you get the right one. You've now spent more time researching what could possibly be in there than you would have spent tearing it down and checking.

What burns me is the parts stores have in stock what I need but in their computer the part is NLA and they do not train the employees to look in the books. I know it has the small bearings and 28 spline axles so it should not have been hard to find the seal,I think its time to start writing down all the part numbers my cars require so all I have to do is go in with the part number from now on.

 

I do exactly that. I've written down every part number that I've used. HAMB calendar is good for that.

good idea.....you should always keep track of part numbers you used and where you used them so you can get them again in the future

 

I am going on memory here, but isn't that a sealed bearing, and the seal inside the housing?

 

Yes its a sealed bearing and the seal is in the housing before the bearing.

 

I'm thinking, maybe incorrectly, that if it is leaking past the bearing, the bearing needs replaced too?

 

Looked in the cabinets in the garage and found one new seal for the galaxie and two for the larger axles that must had been for a friends 64 country sedan or my 65 country squire I sold a few years ago,I am going to get two more seals that I need for future use.

 

National 9568 for light duty, 51098 for heavy duty axle. 1957-72 full size cars. From the 1994 Federal Mogul 510 catalog.

I was 200 miles from the catalog when I replied earlier, and it's a beautiful spring day in Arizona, so the concept of being too cold to work on a car never entered my mind.

 

It was 65 friday and upper 30s today so I was not too motivated to work outside,the seal I found in the garage is 13738 I got from Napa a few years ago,13738 cross referenced to 9568 on Autozones website and what is the difference to a 9569S

 

OD is 1/8" different...

 

That would be ID wouldn't it? It is the axle diameter that is changing, not the housing size. At least on the housings I have worked on you can change axle between 28 and 31 spline with the same housing.

 

Those two numbers he asked about are different OD.

 

Thanks for the input squirrel, I am just familiar with the axles I have worked on. If the seal OD is changing then that means they have different bearing sizes as well, correct?

 

the two numbers are NOT both for the Ford rearends. One is the correct number, the other is a seal he had laying around that he was wanting to know if it would fit.

 

Well, that makes a difference! Ha Ha.
