Outer Limits 4x4 Board

one of my mates has had a new navara 3.0td he has only had it for a couple of weeks we done a mild hill climb and the front diff let go .

he has to wait 2 weeks to get it fixed because nissan has no diffs in australia , it has to come from japan.

so does this mean there has been a lot of diff failures ?

im a mechanic at Nissan and we have not had 1 front diff failure on a Navara in the 4 years i have been there and we have had some navara's with 33's come through without faults

this one just must have been a dodgy one because he has only got small muddies on them and it was just a loose hill no ruts or rocks but they have finally decided to fix it after 3 weeks they way they treated my mate was disgusting
