Question:

What are the axle sizes on the Sport model of Wranglers?

It‘s an 03 and I have heard several different opinions on what they are, from 30‘s to 44‘s and I could not find the specs anywhere online. Any help would be appreciated.

Answer:

The front axle is a Dana 30. The rear axle is either a Dana 35 (oval cover with rubber fill plug) or optional Dana 44 (octagonal cover with metal fill plug).
Dana 30 in the front and a Dana 35 C in the back.
