I have a 2011 lifted jk unlimited on 38 mud grapplers, on stock gears and axles, after the winter as it began to get warm outside I noticed that my differential oil was leaking so before i order a new gasket i would greatly appreciate it if someone can tell me what dana axle is in the front of a 2011 jk unlimited i believe it is a dana35 but I'm not too sure, also it would be great if someone could tell me or send me a link of some good oil i could use to replace the oem oil when i take the cap off. Thank You!

 

The front of a sport or Sahara will be a Dana 30, the front of a Rubicon is a Dana 44 Regular gear oil is fine 80w90

Thank you Soo much i really appreciate it

 

Your stock, so just use Silicone or RTV. The stock diff cover are tin and you'll find it hard to get a seal

 

38s on stock gears with the 3.8 liter, and stock axles? You might want to re gear (minimally) while you're at it.

 

you can trace a new gasket out and cut out. they sell gasket material at Napa. I bought a new one for 9 bucks online and used RTV sealant also,
