Nissan TITAN differential failure requiring complete rear end replacement on Nissan TITAN

Some Nissan Titan owners report experiencing differential failures that necessitate a complete rear end replacement. Early models, particularly, have faced issues with rear axle and differential failures, often requiring extensive repairs. Additionally, rear axle seal leaks have been identified as a significant problem, especially in 2006 models, which could escalate to complete rear axle failure. Some owners have noted delays in turning the rear tires, signaling potential issues like a faulty pilot bearing. The cost of replacing a front or rear differential can be around $3,000, prompting some owners to consider upgrading to more robust aftermarket units to prevent future problems. While rear differential failures are not common, issues such as slack between the pinion and ring gear or problems with pinion or carrier bearings can indicate serious concerns that may lead to rear end replacement.
