I am by no means a Jeep mod expert but it was really easy. Now my lowest breather is the transfer case at 37".
What trans do you have?
And to the OP, you should do a fluid check in your t-case and trans as well because the breathers for those are far below the height of the front and rear diffs.
And just for reference, this is a diagram of a jeep with the AX-5 trans and np231 t-case. So the diff and t-case locations will be the same for all non-Rubicon TJ's, trans will differ however.
