Axle ID Help Please
I just bought a 96 F250 with a 5.8L engine, auto trans and floating rear axle. I read the tag on the axle, there are two lines of data. The top line has S121R and the second line has L55 102 6G26. The last numbers may be 6626. I did not have my glasses with me. From searching other posts it seems I may not be seeing a 3 in front of the L55. Can someone tell me the manufacturer of the axle, if it is a limited slip, what size it is and finally is it possible to install a ring and pinion in this axle for a 1:4.11 or 1:4.10 ratio? I have never installed a ring and pinion but I am a machine mechanic and I have the necessary tools. Thanks for you help!!

The "3L55" on the tag means 3.55 : 1, limited slip.
You can install 4.10/4.11s, whichever fits.
This may be a Dana 60, but others with the real decoder ring will have to tell you.
As for tools, dial indicator, inch-lb torque wrench maybe.. Once you learn the model, you can probably find a "how-to" video on line.
