Sorry guys, but I have been studying this a bit and would like someone to confirm my findings.

I have a 1979 F150 4x4 with the 6.6L engine. The door plate states the axle code is K2A.

I have a partial rear axle tag. The part of the tag under the bolt is folded and crushed. The remaining part that I can read is:

Top line: *FE - AW 9BD
Bottom line: *50 9 366A
* = illegible but small bits of evidence suggests a W on top line and L on lower line.

According to another thread with a look up table with 10 pages of info, I am looking at a Ford 9" with a 3.50 ratio and 31 splines on the axles. Contradicting the look up table mentioned, there is the 366 on the tag, which I believe is the actual ratio.

Is anyone able to substantiate the ratio, locker and spline count?
Is the front high pinion solid axle with open knuckles a Dana 44? Any other data available on the front axle from the rear tag and axle code?

Thanks in advance,

Rick

 

Your sure its a K and not an H? As far as I can tell Ford didn't use a K in their axle codes
H2A= (H2) Ford locking 9" 3.50 ratio 3,750 lb capacity (A) adjustable steering column (tilt)

WFE-AW = Ford 9" 3.50 ratio use parts list #184
9BD= Built 1979, February, 4th week
350=3.50 ratio
9= Ford 9"
366A= Plant code

As far as axles, in 1979 it could be one of two axles depending on whether the backing plate bolts were 3/8" or 1/2". If the backing plate bolts are 3/8" it takes D8TZ-4234-D axles, if the bolts are 1/2" it'll tale D6TZ-4234-A axles. Both axles are 31 spline.

 

The missing top letter is W. The missing bottom DIGIT is 3 (as in 3.50) the 366 is a plant code.

While I was distracted Mike0o0o0 already answered the question for you. At least I feel good that I agreed with him............

Thanks guys,

I went outside and shined a flashlight 10 different ways on the door plate and I can say that it is very possible the axle code is H2A. The trans code is a definite K, which gives a good comparison. I think you guys are spot on.

So with your guidance, the rear axle is identified and I have some confidence for ordering bearings and seals. I'm interested in obtaining an electronic copy of the parts list #184. Is it available?

What about the front axle? For ordering bearings and seals, what is required besides the axle code and description (solid axle, high pinion, open knuckle, 3.50 ratio)?

 

Here's parts list #184, it's two pages long.
Ford rarely ever put the actual front axle info on the warranty plate. If you're real lucky the axle tag will still be on the front axle. It'll be under one of the cover bolts. If its gone there should be a BOM (bill of material) number stamped on, I believe, the driver's side axle tube.

 

Here's the illustration to go with the parts list.

 

Thanks Mike, there is no tag on the front diff, so I'll have to deal with it a bit more slowly and do a parts match.

Cheers,

Rick
