2003 JEEP WRANGLER RUBICON
First introduced in 2003, the Jeep Wrangler Rubicon TJ was named after the Rubicon Trail in the Sierra Nevada mountains. This Wrangler was designed for ruggedness and was the most capable off-roading Jeep vehicle at the time.
To help with its off-roading capabilities, the Wrangler Rubicon TJ featured Dana 44 front and rear axles with electronically controlled locking differentials. There was a switch that allowed for both the front and rear axles, or just the rear, to be locked to help with off-road performance.
