I'm not sure, but it looks to me like an axle with a 2.27 ratio, limited slip differential, and 8-7/8" ring gear. Perhaps some variation of the Ford 9"? Do you know what vehicle it came from? Does it have a removeable 3rd member housing or a bolt-on rear cover?

What is the wheel bolt pattern? This is a rear axle right?

I'm going to go out on a limb and say you might want to re-read the second line. I'm thinking you have a 3.08 7.5" rear out of a Ranger. The "85" in the second line would make sense if it were a "75." All the other codes are in order for Ford's standard tag layout from the early 70s 'til now. Also, look under the bolt to see if a "3" is there and maybe an "L" is next to it. If you have the "L" you have a factory LS unit.

Edit: Upon further research I find Ford did not offer a 3.08 limited slip in a 7.5" Ranger. Ignore the last part of my post above.

Edit Part2: Look here: http://www.therangerstation.com/tech_library/Axles.html all the way down at the bottom of the page, there is a picture of an 8.8 and 7.5 side by side, It's small but that may help.

What vehicle is the rear currently in? Your gallery says you have a 9" in the '56... I can at least tell you that's definitely not a 9."

My guess is that its an 8.8 out of an 80's ford car, or it could be some type of dana rear axle out of a car as well. but if that tag is right you definately have a 2.27 ratio, and those ratios are typical of lager car rears.

Huh? Did we all lose me or something???

Am I being baited? Since when did the 1st line of the build tag ever say anything about a ratio. I'm curious to find out the results of this. Maybe my computer is laying out the post differently, but I see two rows of data with a possibility of a 3.08 geared 7.5" rear on the bottom. The top line was the axle model and build date, not a ratio.

Edit: I'll agree with the possibility of an 8.8 as the "5" in the second row could have been misread.

Please clue the novice in.

you guys are good. that site helped. the picture on the right is the rearend. I went back to the pervious owner but he would have to ask his son-in-law who build the truck.
C or GY-A 2A27
0 8 8 5 V108E

From the top number on the right I believe the year to be 2A27 (1982or1992/january/27).

Ed-

That last row still doesn't fit an 8.8. There should be numbers under the bolt head. and that 5 is really throwing me off.

I'm thinking the row reads 3 08 8 8 V108E. This would make it a 3.08 geared 8.8.

The tag is hard to make out. I'll take a look at the diff again.

The pic of the axle looks to be an 8.8".

Kspilkington is right, the ratio should not be where I was looking (2A27).

Is the wheel bolt pattern 5 on 5.5" or 5 on 4.5"? I think Rangers have 5 on 4.5" pattern.

Please explain the 5.5 or 4.5. I know it has five bolts. Is that the distance between the bolts?

Glen, Cody -sorry for coming off like a bleeding know-it-all, I was floored that both of you even thought of the ratio like you did. I can appreciate the need for an open mind, though. You guys are always the most helpful.

Ed- The 4.5" and 5.5" is the bolt circle pattern. Divide your wheel hub into even quarters, like a clock, with one lug at 6 o'clock. Take the center of the lug and either imagine a lug at 12 o'clock or measure to the back of the lug on either side of the 12 position. It's easier with a 4, 6, or 8 lug pattern, you measure the distance from center to center of the lug that is in the opposite position. The oddball is the 5 lug.

Thumbs up

doing the above it's 4.5.
