ford 9 inch id?
i got a hi pinion dana 44 front and a ford 9 inch rear under my jeep.
i have no idea what they came out of. im not sure if they are from the same truck or not. im putting in gears, lockers, and shafts now. it seems the 9 inch is wider than most though. the rear shafts are 32.5 inches wide from the inside of the axle flange to the tip of the splines. it seems most 9 inch shafts are 31.87 inches wide. it has 1.25 inches of spline inside the diff. its currently 28 spline(not for long), with an 88128 bearing on it(i believe thats the small bearing style). the seals go inside the housing, not on the end of the shaft. they are 5 on 5.5 1/2 ton, disc front, drum rear.
how do i id this axle? is there an axle shaft length id chart somewhere?
are van 9's wider?
any help would be appriecated
thx

this thing has been apart a bunch of times. i see no tag anywhere. it has the common c7aw-e center section. 78 is cast next to the c7aw-e could this be a date code? who knows if this center is origional. it was already regeared to 4.56 at some point. anyone know the bearing surface diameter of a 31 spline 9 inch shaft.

the rear shafts are 32.5 inches wide (in length) from the inside of the axle flange to the tip of the splines.
Parts catalog refers to this as Measurement A, and this is the correct way to measure axle shafts.
it seems most 9 inch shafts are 31.87 inches wide. Not so.
it has 1.25 inches of spline inside the diff. its currently 28 spline(not for long), with an 88128 bearing on it
(i believe thats the small bearing style It's not, it's the large axle bearing).
the seals go inside the housing, not on the end of the shaft. they are 5 on 5.5 1/2 ton, disc front 1976 and later for 4WD's. drum rear That could be anything from 1957 thru 1987.
1957/72's are essentially the same except the 1968/72 shaft is 1/2" wider to accomodate the larger brakes. 1973/87's are wider.
how do i id this axle? By the FoMoCo ID tag, which was at 5 o'clock under one of the bolts that holds the carrier to the housing.
It's prolly missing by now.
is there an axle shaft length id chart somewhere? Of course, listed in all the various parts catalogs.
are van 9's wider? Depends on the year.

Fits: all 1957/73 F100's / Some 1974/83 F100's / 1975/87 F150's / 1969/74 E200's / 1975/87 E100/150's.
Fits: 1961/78 Police Cruisers / 1961/72 Station Wagons with HD rear ends / 1966/77 Bronco's w/ 3300 lb rear axles / 1961/76 Thunderbirds and many other car applications.
Axle measurements: This is a lot of work, because the axle shaft measurements are listed separately from the rear axle application charts.
So I first have to look up each axle, then go to the measurements.
I'll see if I can find what that axle length you refered to is from.
This will take 60 seconds, or 30 minutes, it depends....SEE NEXT POST > >

Try these two out for size, as both are close to 32.5." Let me know what the spline diameter of your axle shaft is.
There's nothing that's 32.5" except for 1960/64 Galaxies (COAZ-4234-A), but the bolt circle is 4.50" on these cars.
1976/78 F100/150.
D6TZ-4234-B .. Axle Shaft-28 spline / Measurement A: 32 7/64" / 1 1/4" spline diameter.
D6TZ-4234-C .. Axle Shaft-28 spline / Measurement A is the same as above / 1 3/8" spline diameter.

the shafts have alot of spline in the diff so if it was a hair shorter i can live with it.
when i said most are 31.87, i meant if you look for alloy or cromo shafts that seems to be a popular size they offer for late 70's ford trucks and full size broncos.

thx for the help! ill mic the spline diameter for ya.

The previous 9's are shorter. These 1957/72 9's are popular with peeps that own 1948/56 F100's because this axle fits like it was made for them.
The 28 spline axle shafts used 1968/72 are 1/2" longer than the 1957/67's because Ford increased the rear brake shoe size (FINALLY!) from 1 3/4" to 2 1/4."
9" introduced in 1957, cancelled after 1987.

Ford like all the other automakers is really in the partsbiz, and the parts generate faaar more profit than vehicle sales do.
The 8.8 integral rear end was introduced in 1983, it replaced the 9 in practically every application thru 1987, and is the only rear end offered after 1987.
The 8.8's are cheaper to produce than the 9's, and break, while the 9's are practically indestructable.
8.8's were also used in "light duty" F250's from 1983 thru 1989.
The last year for the 9's in some cars was 1979.
It was replaced in the big Ford's, Merc's and Lincoln's by the (weak) 8.7 WER, a distant cousin of the 8.8 that was first offered in 1967. These cars eventually got 8.8's later on.
