Greetings, for those of you who read my post on the GUIV Clunky drive train. I took it back to Nissan today for inspection, they found out its coming from the rear diff and happens as soon as you put any load on it.
Anyways the dealer is contacting Nissan for further advise, (probably trying to see if Nissan will approve a change of diff cntr.) as there was talk of this being a possibility, or change of oil....Big difference between the two, they obviously are winging it..
What I'm concerned about is that how can a 2005 mod 4.2 T/D with only 6,000klm on it have a diff problem, especially when they have a reputation for being the "strongest" in the drive train area!!!
mmmm....Any thoughts?
Regards,
Babs.

strong parts are of no use if they were put together on an assembly line including 1 guy who was stressing out how to tell his parents his new partner is the same sex and another who is hung over after finding out his wife is pregnant to another man and he is unshure now if the one he already has looks more like the paperboy or the milkman. My point is with the amount of vehicles churned out i am amazed there are not more problems like you describe. It is not however unknown. the first 79 series we had on site lasted a few days before the clutch crapped itself

Interesting out look Davoe, I get your point shows were only human there is error straight away, no ones perfect ay....
Correct me if I'm wrong, I thought most components were put together by machines, (I'm more than likely wrong.) Never seen a vehicle put together, but would love to tour a factory to see the inner workings....

Depends on the factory and the part. i had a freind that worked in holdens and they had both. But even machines have to have there parameters checked and tools/bits checked for wear etc. Also most likely (If the diff is stuffed) it could be using parts from a contactor. (alot of parts for new cars are supplied llike this monroe,aunger etc) a bearing could have been manafactured using a tool that is worn ouside of specs etc

On a production line there are tolarances (as expected) and sometimes there will be a vehicle that has max tolarance on multiple parts. Inspectors may note this but it is far cheaper to send the product out into the big wide world and hope that everything is ok then it is to strip it down and do a rework on it. Production lines make new items and do not have time to do repairs! Some manufactures of small items just build in a cost factor for replacement and offer a swap for faulty goods - give you a new item and throw the returned one away.

I have a 2003 4.2 Patrol. Took it to Ultratune for a service and they gave me a printout of the requirements etc. A footnote from Nissan at the end of the printout warned about rear diff 'judder' if the incorrect oil was used and recommended they discuss the problem with the customer before changing the oil due to the expense. Ultratune advised me to use LSX90, which I have done (both front and rear) and have had no diff problems. If you have an Ultratune dealer handy ask them to look up the requirements in their system (the details were listed under the 80,000km service for my car)
Good luck
Peter
