I am getting ready to purchase a new nine inch housing for my 66 and need some help. I already have a 9" center section and axles (from my 8 inch) so I am buying just the housing. my question is in regard to the housing ends. When I talked to the shop they wanted to know if I wanted big or small bearing ends. The cost is the same should I go with the big ends? and if I do what does that mean for my current axles/backing plates. I assume I will need the big bearings for the axles are they interchangable? Also will the backing plates I have (from the 8") work or will I need different ones? Thanks for your help

i personally would go with the big ones. because you can get backing plates that just drop over the axel and do not have to be part of the press on procedure. there is big and small and the torino size. stay away from the torino size because the bearings etc. are hard to find. if your axles are the correct spline, i think they might work but dont take my word for it.
good luck

I just bought a housing from Currie, the housing ends are Mustang size (small bearing) your axles take the small bearings as do your brake backing plates, if you end up with 31 spline axles and carrier you can get bearings to fit the small ends (Cobra Jet Mustang bearings)but not the other way around (small axles big ends) Call Currie and talk to them, they built me a new housing and shipped it to my door for $330.
Their housings look great, beautiful welds, took a couple of weeks to get it.

Thanks for the info. I called Currie, that price is way lower then what the local shop wanted (and it turns out they buy thier kits for currie). Anyways according to the guy at currie if I want to use my current axles I need to go with the small bearing ends. So that it what I will be doing.

thanks

Just an idea here. If you are going to have a housing made, have them put the "New Style" Big Ford housing ends on it. These are also known as Torino housing ends.

You can get bearings that will mate your 28 spline axles to this type of housing end. The benefit is this: If you ever want to upgrade to rear disk brakes you can do it cheap and easy. The rear disk brakes off a Ford Explorer are a direct bolt on swap with these housing ends. The Explorer uses an 8.8 rear, but also has the same housing end. You can get the brakes in a junkyard or buy them from Ford. Ford has a brake kit with all new parts for around $360.

You can be set up for a future brake swap for only the cost of new axle bearings. Much cheaper to do it now.

Dave,

Are you sure about that? When I talked to the sales guy at currie he said that in order to use my axles I had to use the small bearing housing. I also talked to him about the explorer brakes, they sell it, and he said that you need the new style housing that would not work with my current axles. Also would the new style work with my current brakes?

thanks

That's the same thing he told me, I wanted the Explorer brake set up for mine. ??
The Stainless Steel Brakes conversion will still work.

I have seen 28 spline axles used with the big bearing housing ends, so I know the bearings exist. The rear end in my race car came from a 72 Ford truck. Most trucks came with 31 spline axles, but not all. It had an open 3.25 rear end with 28 spline axles, and it also has the big bearing ends. I reused those when I narrowed the rear, but I upgraded to 33 spline axles so I needed different bearings. A buddy of mine still has those axles. The next time I visit I'll see if there is any kind of part # on the bearings.

The new style housing ends will can be made to work with a little drilling/grinding.

The bolt pattern for the bolts that hold the backing plates on measures 2.00" (vertical) by 3.375" (horizontal) on the small bearing ends. The new style big bearing is 2.00" X 3.562". The backing plates have an indented area that is sligtly larger than the housing ends. You have to grind the outside perimeter of the new style housing end to fit within the indented area on the old backing plate. Then bolt the backing plate on. Only two of the holes will line up, but when you tighten them up the housing ends will provide a template to re-drill the two holes that don't match. Then you can use a die grinder to open up the center hole in the backing plate from 2.835" to 3.150 so the bearing will fit through. A little work, but it can be done.

I'd call Mark Williams or someone similar.

Dave,

you are correct they do make a bearing that will let me do this

Now you have started a whole new questions for me. Following the how to you listed for the brakes wouldn't this method cause the backing plate not to be centered? I know it is only about a 16th on an inch so does it not matter?

thanks for your help

Oops, my bad. Forgot to mention that the bolt holes on the two that lined up (almost) need to be slotted with a die grinder.

It takes a little trial and error but it will work. I helped a buddy of mine set his up like this a while back. We put a 9" of unknown vintage in his 69 Mach I. We used his original brakes and the "Torino" housing ends that were on the rear when he got it. The main thing is to get the backing plate centered so that the brake shoes contact the drum fairly evenly all the way around.

That pic of the bearing from Mark Williams. It has a O-ring on it. I've seen that before on 9" bearings, what does it do though? Guess what I mean what does it seal that isn't already sealed?

Just so you all know, the bearing for Mark Williams is not the correct bearing- that one is put larger axles in a small bearing end. MW does not carry the other but a company called Dutchman motorsports does.

Most of the bearings sold by the performance axle companies like MW and Moser now have the O-ring seal. It lets you do away with the factory axle seal that is up inside the housing. The o-ring seals against the housing ends.

Not a big deal with 28/31 spline axles, but a must have if you run 33,35 or 40 splines. These larger sizes (I run 33's) are larger in diameter than the hole in the middle of a stock axle seal.

And the O-Ring types are more prone to leaking too.

If you are trying to use factory Mustang axles , use small bearing housing ends.

The large bearing, small bolt housing ends ...called "Torino" for whatever reason, they are more commonly used in 80's 1/2 tons... are a good choice if you are using large bearing axles in that it allows 11" drums, 10" drums (from mid 70's Torino) or discs like the Explorer setup.
