hi everyone, ok heres the deal i seen someone with axle codes in there sig so i checked mine the next day and when i came back to the forums i cant find the persons sig. cmon who is it show yourself!!!! lol.. on another note i dont know if i looked at the right tag the one on the drivers door is missing but i looked on the one with the tire specs/load specs is this the one? if not i have a tag here that fell off quite sometime ago and i have no idea what it came from i am pretty sure it came from the axle when i changed the seals.. i have a pic if someone wants to look at it and tell me what it is and what it means, it looks to me like its the vin and then theres a bunch of spaced out numbers below..

It's Good Samaritan.

Post up a pic of the tag, I'm sure somebody here will figure out what it is.

i think i may have 2.47 good or bad? i still need a answer on where the axle code sticker is besides the one on the actual rearend.

[LTDMan83]

2.47=bad,The only other sticker that has the axle code on it will be on the front drivers door above the latch.

[cld783]

great thats the tag missing from the door so obviously i was looking in the wrong place. ok lets say this tag that i have is the axle tag which i think it is, where and what numbers would i be looking for?

the tag i have has lots of numbers on it most likely the vin? with a second row of spaced out numbers below is this right? i cant get my digi camera to work right so i can post the pic and i looked online and couldnt come up with any specifics for our cars.

This is a diff tag.

[cld783]

hmmm mine dont look nothing like that but im pretty positive it came off the rear end. imma get this pic on here and see what you guys think.

2.47s couple those with an AOD and and 31" tires, probalby get nearly 30 MPG on the highway.

2.47s? Is you car '83 or older? That sounds like a gear out of a C4 equipped car.

Not on 1,000 years. You would be turning WAY too little RPM's for peak efficiency. If it was that easy, manufacturers would be doing it. They knew it didn't make sense when they gave up on it in the early 80's.

Heh... we got a '76 Cutlass Salon with a factory 5-Speed Manual. It's got something near to 2.56:1 and combined with the OD and 260 V8, it's a complete dog. 5th gear is unuseable unless you are going 70mph+.

[cld783]

i was looking at the wrong thing, its not 2.47. i have no idea what it is yet cuz the tag i have looks more like a vin tag so im confused
still tryin to figure out why my digital cameras not being detected once i figure it out ill post a pic..

Here's another pic of the axle tag, should be on one of the bolts for the differential cover unless you lost it changing the seals. The sticker is not on the door itself but on the inside right below the door striker. It will say AX on it somewhere and have a letter referring to the axle code (example: Y for a 3:27 open).

You could jack the car up and count the number of times you have to turn the wheels to get one turn of the drive shaft. Also, you could probably call a local Ford dealer and ask them to run the vin for you. There's also a report you can get to see exactly what your car came with from the factory.

To narrow it down, chances are your car has either a 2:73 or a 3:08 rear. Most box panthers were sold with these types of rear-ends, alot were open rear differentials also. The 3:55 K-code rear was very rare to be found on a panther unless you requested the full-tow package, but is found more often with Lincoln's from what I've seen. 3:27's were an option also, which are the gears I have and can be found with alot of tow-packages. I like my 3:27's, only wish I had a track-lock rear though.

Also, you will know that you don't have a track-lock if you can spin the right rear tire only while attempting to powerbrake the car.

thx mefull your information was very usefull, I appreciate it. almost 99% of the time it burns both tires but i do know it does one more than the other because one tire has a bit less tread. could this be from wheel spin on launch? with tracloc does it always spin both tires under power brake or does it just depend on how good the power brake was lol?

maybe ill have to do some research.. i understand what limited slip is and all that but whats the tracloc. thx for your time.

That tag looks oddly like the one on my car, and the pic I took of it..
