I have a 89' f250 lariat extend cab with a 460.
want to know what these numbers on the tag on my rear axle mean?
V126C (top row)
55 10 2 9D18 (bottom row)
this tag is on the pumpkin

 

i had the same question this week. Try http://www.badshoeproductions.com/rear.html#id they have pics of different rear axles for Fords. Also count bolts the bolts on the axle pumpkin? What's the AXLE number on your door post?

 

Also go to Artical/Specs above or
https://www.ford-trucks.com/article/...r_Decoder.html

 

Have to get back on the door post numbers. but will try the site you mentioned.

 

3.55 non limited slip? Code 19 on door tag
Edit sorry thats for a F-150.

 

yep, the bottom row 55 10 2 9D18
is most likely 3 55 10 2 9D18 the 1st number is hard to see as it is close to the bolt.

 

Yes and it is a 10.5 inch ring gear and it was made on 18 April 1989.
I think it is most likely 3 55 10 5 9D18.

 

a 10.5 in a F-150? that year it would be an 8.8 unless someone swapped the axle to a 1ton.

 

Ford had alot of differnt 3.55 axels between 1980 and 1986 for the F-150,F-250 and F-350's. And that decoder is extreamly limited and doesn't cover 1/8th of them. Heres my list of 3.55 codes.
Axle codes:
F-150/250/350 Non Limited Slip:
Door Code..Man...Size.......GVW..Gear Ratio
19.............Ford... 8.8"....3750......3.55
26.............Ford............4050.......3.55
29.............Ford............5300.......3.55
49.............Ford............7400.......3.55
69.............Ford............8200.......3.55
Axle codes:
F-150/250/350 Limited Slip:
Door Code...Man...Size....GVW....Gear Ratio
H9.............Ford........................3.55
B6.............Dana........................3.55
C9.............Ford.........................3.55
F9.............Ford.............8250......3.55

 

For an 8.8 the tag number would have to be 3 55 88 9D18.
I was just going by the tag number.
I wish to would have included the top line so I could have looked it up with the code.

 

Sorry, was just giving a better list then what Mike L posted for the FTE's incomplete decoder.
My list still needs a little more info for it but it is work in progress.

 

Okay im back with the door code and it was a ( 39 )

 

V126C (top row) = Ford Tr. '87-91 F250 3.55:1 10.25 NL
or Ford Tr. '87-91 F350 3.55:1 10.25 NL
55 10 2 9D18 (bottom row)
55 = 3.55:1 Ratio
10 2 = 10.25 Ring Gear
9D18 = 18 April 1989

I do not think this is the rear end that came with this truck so you door tag numbers will not do you any good.

The above information is from "The Hollander Identification Manual".

 

Subford--- Do you know what may have come with my truck?
89' f250 lariat extend cab with a 460. So it sounds like the 39 on the door does'nt
match with the numbers I first supplied.

 

OK I reread the thread, where did that guy come up with F150?

Ok, yours is a F250 this makes more sense. This more than likely is the original rear end and what I decoded would be correct.

V126C (top row) = Ford Tr. '87-91 F250 3.55:1 10.25 NL
or Ford Tr. '87-91 F350 3.55:1 10.25 NL
55 10 2 9D18 (bottom row)
55 = 3.55:1 Ratio
10 2 = 10.25 Ring Gear
9D18 = 18 April 1989

The Door 39 decodes to 6250 lbs. 3.55 Ratio and that matches the rear end tag.
