Trying to get some gears for what I thought was a 9”. I have always thought if you have to use a box wrench to remove the lower 3rd member bolts that was a quick way. Reputable company told me ford never made a smooth dish back 9”. Any help appreciated.
This will help.. The KevinStang You Tube info. below is the best on Ford 9 inches you will ever find. Read the links below this video. He knows his Fords rear ends. and https://thevintagemustang.com/kevingstangfordnineinchdiff/ and https://www.vintage-mustang.com/thr...-kevinstang-denver-i-just-came-across.473738/
It probably has a drain plug under the center section. If it does it's out of a '57 Ford. I have one like that out of a '57 station wagon under my Model A. This might help. https://www.therangerstation.com/tech_library/9InchAxles.shtml
My 9 inch out of a 1959 Edsel is smooth backed like your picture. I think they were like this from 57-59, had two dimples from 60 to 66, and a raised section for the ring gear from 67 up. Early models also had drain plug in the housing. Some had a fill plug in the rear. Later models had the fill plug in the carrier.
55 Ford... But after looking at it again I agree with Sidevalve that it is a 9" out of a 57. Thanks all for responding
Some info I found from the ranger station...After double checking the rear of the axle housing it does not have a perfect dished rear cover, it for sure has a 2" flat band running from top to bottom that you cant see in the pictures which is why it might have been hard for the reputable company to identify, also it's 1 year only so I'm sure a lot of people have not seen it before. Thanks again everybody for the help. How To Recognize 9-Inch Housing Centers: 1957 - no dimples, flat center band up the center of the rear cover, bottom drain plug 1958-1959 - two dimples on back of housing, flat center band, some had drain holes 1960-1967 - two dimples, flat center band, oil level hole in back cover 1963-1977 Lincoln, LTD, Thunderbirds had 9.375 inch centers, housings were cut away at the gasket surface for ring gear clearance, one curved rib at the front top portion of differential, strong but no gears
Ranchero and wagon have large axle bearings, quick way to tell is 1/2" backing plate bolts, all others are small bearing, 3/8" bolts.
I think that's the predecessor to the 9"...the Ford rear used from 49-56 in regular passenger cars (not trucks, wagons, or Tbirds). You can tell by the round shape, not oval.
Yep, that's a 49-56 rear axle. The other giveaway is the u-joint flange, that style u-joint disappeared in '56 also. The '57-58 9" housing had drain plugs, those were gone after that. Ford went back and forth on the case/housing fill, with housing fill being more common in trucks for some reason, but certainly not exclusive to them. The smooth back /case fill type was mostly '57-58, but housing fill smooth backs existed into the mid-60s. At one time I thought it may have something to do with whether the housing was a small bearing or big bearing axle housing as housing fill seemed to be more prevalent on big bearing housings. I don't recall seeing a dimpled housing fill, those were all smooth-back. The one the OP shows is very probably a '57-59 small bearing housing, no drain plug rules out the '59. That's a WAR case for sure.
That isn't a 9 inch center section. All 9 inch differentials have a removable pinion bearing retainer.
