Here is a more inclusive list of axle codes for 80-89 pickups. I noticed the one in the Tech Articles is lacking some codes. I also have axle,transmission,engine,assembly plant,and year codes for 90 and newer models also. Should they be put in the Tech section?

THE FIRST TWO DIGITS OF THE AXLE CODEIDENTIFY THE RATIO AND CAPACITY OF THEREAR AXLE.THE FOLLOWING CHART LISTS THESECODES, THE CORRESPONDING RATIO ANDCAPACITY AS WELL AS THEMANUFACTURER'S NAME AND MODELNUMBER.

Holy crap dude. Where'd you get all that from?

 

Thanks For The Info About Axle Codes, Would Like To See The Info For 90 And Newer, I Had A Previous Post Regarding Wanting Codes For A 93 F-150 4.6 E40d With A 3.o8 (18) Into Which I Want To Place A 3.73 Or 4.10 (this Is The 8.8 Axle) I Was Told That Ford Did Not Install Anything Higher Than A 3.55 But The Ford Dealer Says Not So, 4.10 Was Available But He Could Not Tell Me The Code. When Walking Through The Junkyard I Would Much Rather Look On The Door Jamb Then Crawl Under The Truck. Also, I Note That In Your Guide #18 Is A 3.08 But Is This Stillthe 8.8 Axle And Will This Earlier Year Diff Fit In A 93? I Notice A Lot (13, 22, 25, 32 Etc) Having 4.10, Butwill They Fit The 8.8 In My 93?

i got an M9 code on a 90 ford f-150 4x?? any ideas?

 

That's probably an 'H9', 3.55 limited slip. The axle tag should read '3L55'. The '3' may be partially obscured by the cover bolt.

 

that is awesome, post everything you have if you have the time. (that probably took some time to type)

 

Wow thanks for the info guys. My 84 f-150 says I have an H8 axle which says is a 3.08 3.75m L/S axle . I guess searching this site for info does really pay off. Now if I can just find out what K means as far as transmisssions go. No need to reply I'll search for it.

 

i think a k is a c6

What does the D stand for? I know the 24 says I have the 4.10 rear gears. This is off the vin plate on the door. The truck is a 64' F260 with a T18, spicer 205 Tcase model 24. Does the model 24 on the Tcase the same as the axle 24? I am getting confused. All I do know is that this truck will drive up a wall in 4wd. One more thing, what is the front geared at? I believe everything is stock. Any info is appreciated. I am learning a lot on your great sites. Thanks. You can see the truck on my gallery.

 

Mark and Janet,

On the 4wd transfer case, a '64 F250 would only have a New Process NP205 t-case if it was swapped in, since the NP205 didn't come out 'till around 1970. It could have a Dana/Spicer model 24 t-case stock, since those were used in F250's up to about 1972. It should be a divorce-mount t-case with a high and low gear, iron case, part time, gear drive. The 205 also fits this description but can be either married or divorced.

The t-case model 24 doesn't have anything to do with the axle. The rear axle could be a Dana 60 and the front a Dana 44. I'm showing axle code 24 as a 4.10 ratio. Maybe the 'D' means limited slip?

 

Thanks for the info. You clarified a lot. Keep up the good work.

 

the tag on my axel looks like this
WDM-C 9GD
2 75 G 314A
any ideas what it is its a 1980 F-150

 

That's a 2.75 ratio. Should be an open differential in a Ford 9" axle.
