1993 Other Nissan Models

Hi there,

Differentials are very sturdy items and normally give you may years of trouble free operation, the most common cause of failure is low oil due to a leak, wrong oil used, contaminated oil usually only with X's that do river crossings and don't check for water ingestion from the breather, incorrect bearing & gear set pre loads and clearances, this is not common but can be the case if re built by a unqualified person that dose not understand the importance of the correct set up procedure, and of course just plain wear and tear, I hope this answerers your question.
