hi didnt hav to work today after all so far.so i went to get gear oil and guy at store had a lot of ques i couldnt answer so i wrote down the numbers on the tag and i dont no what they mean. looked at a decoder thing and the only recognizable thing was the number 12 which means 2.73 gears i think. and those gears means this is slow right? here is what i think i saw(6's could be c's or maybe G's) thanks extremely I NEED TO NO IF ITS LIMITED SLIP OR NOT,AXLE TYPE FOR CAPACITY ETC THIS IS NEW TO ME.
SS1206
3L55 10 2 4601

 

ok the 3L55 means limited slip got that now

 

3L55 = 3.55-1 w/Limited Slip

 

thanks alot anyway to tell what axle size i have? the guy said i need to no in order to tell how much fluid i need, but i can just gage that with my finger i think?

 

What's the year & model of your truck?

What's the AXLE code off the Certification Label?

You're posting in the 1987/96 forum, but your signature sez 1997 F250 HD.

 

yea i post here cause i have the old body style so its basically the same as a 96. my door panel doesnt match my axles because they are from a 94 f350

 

Try going this route,

Axle Identification Chart

 

BINGO 10.25 HOPE I GRABBED ENOUGH gear oil thanks again this is now resolved too

 

The 10.25 takes 7.5 pints.

 

thanks i got it back together with no leaks
