Capacities for a GU wagon (I.d imagine they're the same driveline/gearbox):
Gearbox - 3.8 litres
Transfer case - 1.9 litres
Front axle - 5.4 litres
Rear Axle - 2.1 litres
(Info from Vehicle handbook)

Thanks Rob,

They don't have these specs in my hand book.

They look similar to the RB30 GQ patrol I had.

Funny how the rear diff look similar in size to the front but takes much less oil.

Have a look at the Penrite oil website and go to the links to choose the right oil for your car. Not only will it give you the correct volume but also the recommended gear oil to use.

Hi

Make sure you use the correct oil in the rear diff as I am pretty certain that all GUs have a LSD.

You need SAE 140 LSD Oil API GL5/6

Plus an additive for LSDs which costs about $13

Nissan and Penrite can supply the correct oil and additive. I would expect the major oil companies would also carry a suitable LSD oil.

Don't use a multi grade as it may cause damage to the LSD in the medium to long term.

Cheers
Phil

If you use LSD oil, the additive is included in the product. If you use EP oil, you must add the additive.

Castrol LSX 85/140w is what I've been told to use by our local dealer's spare parts. He's a mate and they have been using this oil in the Nissan rear diffs.

Hello David and Justin and Madcow

I am just passing on advice following the troubles I experienced with my diff about 10,000 kms after replacing the oil with multigrade as recommended on a well known oil company's web site.

The diff developed a shudder when starting slowly from standstill with the steering on full lock to the right. Other GU drivers have experienced the same problem. Search the archived forums on this site.

My Nissan owner’s manual and Gregory's Workshop Manual both specify API GL-5 SAE 140 + LSD Friction Modifiers. A Penrite Representative told me to use the friction modifier and that he had received many enquiries about the LSD lubrication from Nissan owners.

A near neighbour and owner of a Transmission Repair and Rebuild Business with over 30 years experience told me to always take notice of the Manufacturers recommendations because there has been significant developments in lubrication technology and metallurgy in recent years. He advised using API GL-5 SAE 140 + LSD Friction Modifiers.

Hope this helps
Cheers
Phil

Phil

There is some confusion here. The fact that the oil is multigrade ie. 85W/140 as apposed to stright 140W is not the problem. Multigrades are fine to use in the GU as far as Nissan is concerned. The problem is you can't use a straight unmodified EP oil such as used in all other diffs. It must have a friction modifier. The Castrol oils and others marked with LSD or similar notation such as Penrite Limslip have the modifier already in them, so no more need be added. If however you use a normal diff oil such as an EP 140 or an EP multigrade such as 85W/140 then you must add the modifier.

Speaking about oils....do they have a shelf life, ie can I leave them sit in the back of the wagon for 3 months/12months/2 years etc???

Can't see it would be a drama, I would have thought the main problem is if they are subjected to heat or the container is left open.

The oils last for 40 000km in the diff. That's an average of several years of abuse before changing. I wouldn't think a few months in the back of the fourby would do any harm at all.

Austravel do an archive search and type in "limslip 140". About the correct oil to use for the rear diff.

Thanks Barnesy, I've always used Castrol LSX 85W140 in my GQ. Now have a GU and will use the same oil. What I was trying to find out was the different capacities needed, especially the rear diff. Physically the front diff looks similar to the rear but from the post above it only needs half the oil.
