Lloyd, I'm sorry you've had a terrible experience with Nissan. Nissan of just 3 years ago did not have this type of problem; I have yet to hear of anyone destroying an H233B rear differential. The newer vehicles Nissan has been putting out in the past few years have been geared towards the majority, and not the wheeling minority. Unfortunately, it's created rigs that do great on pavement, but are severely lacking in strength offroad, or for heavy duty work. It's unfortunate, but it's been working for Nissan on the sales end, so I don't see them changing their target audience in the future.

You'll probably get bashed for saying negatives about Nissan around here, so please, do yourself a favor and keep any negatives to the 05+ models, as the previous models do not suffer from this weak condition!
