Saunders, that was in Mission Hills?

All the drivers came to Crenshaw, so if you did, I was there from 1975-1985.

The 9" axle seal of EOTZ1177C has been replaced (again) by EOTZ1S177CA and is still available from Ford

MSRP: $7.00 / FTEpartsguy.com price: $5.04

Havi, you can email me off FTE.

 

You are correct!!! I worked for them from 79-80, so we crossed paths. I use to hate going to Crenshaw Ford too... LOL... We did have to make several runs to Crenshaw, I recall that. I had to make several trips to Universal Studios also. Don't tell anyone, but I took the parts truck on the Jaws ride and it activated it. Scared the heck out me when the truck tipped and that fake shark came up, I had a friend along (wasn't suppose to be there) but it was fun! I can't even begin to count how times we delivered the wrong parts. LOL... Back then, the Mustang trim parts were a popular item. My best friend worked for Sunrise Ford in Tujunga, CA. Little trivia here.... Prior to Sunrise Ford, it was called Welman Ford. I recall my dad purchased a new 66 Mustang in 1967 there. It's the same one sitting in my garage. Still have the license plate frames from that dealer also.

 

You might remember this, it happened sometime in 1980.

The newbie parts driver from Cutter Ford in North Hollywood had just picked up his daily parts from the Ford parts warehouse over on Sheila Street. He parked outside the service lot at Crenshaw, and left the keys in the ignition. When he came out, yup, you guessed it...the truck and all the parts were gone.

I loved working at Crenshaw (back counter and wholesale phones), which has now closed. Because it was such a busy place, the day went quickly.

I added more info to the post above inre to the 9" axle seal.

 

........sorry...but I didn't start it......I was told this nine I just picked
up came out of a '70 F100 w/ 3.50 gears & was detined for a '67 mustang project but a heart attack changed the PO's plans...he's gettin' better so my gain...here's the skinny:

Just want to know "more" of what "it" really is...

It has 11" drums with 2 1/4" (maybe 2 1/2"?) wide shoes, 2 holes & 1 dimple on the axle flange (31 spline?), brake drum
fficeffice" /><O></O>
backing plates require a 9/16" socket (large bearing?).

Here are some casting numbers:

C5AW-?

Date Code: CF29

 

If its out of a 70 F100, the number you posted doesn't make sense. The C5AW would mean it came out of a 1965 Model, maybe a truck? If the 3rd member has a tag on it, you can see what gearing is in it and other information. Should say 3.73 or 3.50 or?? If not, you can make a mark on the yoke of the 3rd member. The turn the lug on the wheel, one complete turn or 360 degrees, and count how many times the yoke went around. If it went around 3 and half turns to your one revolution, you probably have 3.50 gears. If it goes 3 turns, they are 3.00 etc etc... Not sure on the holes and dimple on the axles? The holes are standard and used for or with the socket to align with the axle flange bolts, so you and remove them and pull the axle out. The pictures don't really show much on what type of rearend it is. Maybe you can post more?

 

Ed,

I think you're right in saying its about a 1965 or later. I think the 57-63 or 64 truck rear diffs had the shock mounts on a plate held on with the "U" bolts and didn't have the seperate brackets for them. I know my diff came from a 1960 F-100 and I had to weld on lower shock mounts.

Please don't take the following as a rant, or belittling you...I've had to correct this mis-conception 100's of times on FTE.

You cannot go by C5AW to ID the year....you cannot!

This is a very common mistake here on FTE because ppl think that the casting number only refers to one year, it doesn't.

Ford used the same numbers for many years, so forget about trying to ID anything using these marks!

Besides, casting numbers cannot be cross referenced to actual part numbers.

It could be a 1965, it could be a 1972. Hell, it could be a 1987!

All that number refers to is the year it was first cast.

Cars/trucks shared many of the same parts, so even tho the casting number refers to a 1965 GALAXIE (third digit of A), the same part could be used on anything.

This isn't a Galaxie rear end from 1965 (and later) because they have rear coil springs.

And just because it was cast in 1965, that doesn't mean that it was for 1965 and later.

Ford needed to cast more, so the same casting number might be for a part that fits 1957, 1967, 1977, or 1987!

Where is it marked C5AW, on the carrier (pumpkin)? If so...here's the real info:

C2AZ-4141-B .. Carrier Assembly / fits: 1961/69 passenger cars (with large wheel bearings) & F100's / Some 1970's, all with 28 splined axle shafts.

Ford changed the dif bearings midyear 1970 to the "slim line" type.

See...just what I said...the carrier was cast in 1965, but the part fits 1962/70!

31 splined axle shafts were introduced in 1968 AS AN OPTION on F100's. Most 1968/72 F100's do not use this rear end.

The carrier/housing, most of the internal parts are not the same as a regular 9 uses, because the ring gear is 9 3/8" in diameter.

> > 2 1/4" rear brakes = 1968 thru 1983 F100's / 1975 thru at least 1991 F150's. I'd have to look and see, but the brakes prolly fit 1992/96's as well...and Bronco's beginning in 1978.

 

I'm not offended, heck I'm only a parts driver!!! LOL.... What do I know? I'm just thankful we have someone like Numberdummy in this website.... Now I'm really confused though, I know my rearend is the big bearing type and supposedly from a 1960 F100. It has the leaf spring mounts on it and not coil spring types like the galaxie you mentioned. If it was a 1960 rearend, the bearings should be the needle type cone shaped bearings for that year axle, correct? I recall my bearing are the sealed bearing type (I think you referred to them as slim line), but I still have the big bearing type housing/ axles. (I know because my disc brake conversion worked with that kit). Does this mean someone may have replaced the bearings with sealed bearings? Would that make a difference on ordering a oil seal for the housing? Maybe someone switched out the axles for a newer year? Are those interchangable? Lots of questions, but they make sense??? I think????? LOL...

 

You seem to have a mutt...not surprising since the truck you got it from is 38 years old and has had how many owners.

And...is it from a 1970, or was it in sumptin' else before?

P/M me your address, I'll come over at your convenience and take a look-see.

9 inch: 1957/73 all the F100's used the large axle bearings. In 1970, Ford changed the differential bearings to the slim line (tapered roller) type. 1974/78, some 9's use the combo tapered axle bearing/seal combo.

The axle seals are the same 1957/73 & 1979/87. Many 1974/78's use the same ones: Originally: B7A-1177-A / part number updated several times (typical of Ford), so now: E0TZ1S177CA.

Some 1974/78's used the combo axle seal/bearing (D4AZ-1177-A-seal only or D4AZ-1225-A the whole tamale).

But after 1978, that bearing combo wasn't used anymore (it was crap, really designed for the cars and didn't hold up worth a damn on F100/150's!).

Same-o same-o 1957/87: The pinion seal, pinion bearings and races, the crush sleeve and O ring, pilot bearing and retainer, housing gasket, the R&P's will interchange,

Depending on the application, the housings and carriers, case, spider and axle gears, dif bearing and races, the axleshafts aren't the same for all these years.

The axleshafts are the same 1957/67. Identical part number, R/L is the same.

1968 and later are longer to accomodate the larger rear brakes.

By the way: 1957/72 F100's the rear springs interchange. Same length (24" to eye bolt / 28" to eyebolt), same width (2 1/4"). The number of leafs changed, but a spring from a 1972 fits a 1957.

 

YOU dudes ROCK......THANKX...I'll drag this puppy out into the sunlight over the weekend & get some better shot take some better measurements
so we can figure it out! Get some in-laws in town for a few dayz so gotta play the "game"...dont mind tho...will get the pics up asap...might mot be 'til monday when "things" cool down..ND & lwr2 & everyone...again for ALL your help!!!

 

wow! that is some killer info that gets shared here on this site. thanks.

 

Bill,
Great info for many of us, Thanks!
