I had read in a magazine publication that the Mojave got "thicker axle tubes".
While this is technically correct, it seems they're leaving out some context.
This article says that the axle tubes were designed with the Mojave in mind, well before anyone knew there would be a Mojave package, and thus the Rubicon got the same axle tubes as a side benefit:
Jeep has been contemplating the Mojave package since the early days of the Gladiator's design. In terms of the 3rd Generation Dana 44 axles found under the Gladiator off-road packages, it's not a case of Rubicon influencing Mojave as much as Mojave influencing Rubicon. To better cope with the rigors of pounding through unforgiving terrain at speed, the Mojave front axle required an increase in axletube wall thickness to 10mm, which is thicker than the Rubicon technically required. So Rubicon can thank Mojave for its 10mm axletube wall thickness. Rubicon features lighter weight-saving aluminum knuckles, but Mojave needed high-strength cast iron knuckles to better survive impacts at high speed and other rigors of desert prerunning. Also, where the Rubicon has a Tru-Lok locking diff up front, the Mojave runs an open differential. The rear axles are the same for Rubicon or Mojave, both sporting 4.10 gearing and electric Tru-Lok locking differential, but Gladiator Rubicon can be ordered with optional 3.73 axle gears, while Mojave comes only with 4.10s. So, to recap, the Rubicon package's front axle is the wide-track 3rd Generation Dana 44 front with 10mm axletubes, aluminum steering knuckles, 4.10 gears (3.73 optional), and Tru-Lok electric locking differential. The Mojave package's front axle is the wide-track 3rd Generation Dana 44 front with 10mm axletubes, cast iron steering knuckles, 4.10 gears, and an open differential. And both Rubicon and Mojave packages' rear axles are the same 3rd Generation Dana 44 rear with 4.10 gears (3.73 optional for Rubicon) and Tru-Lok electric locking differential. -Truck Trend
