In my car the front and rear diffs use different fluids. The rear is the electronic locking unit and takes a special fluid.

Front: LR019727
Rear: LRN7591

So, looks like I'll get to do a bit more cleaning between components!

Thanks again!
Larry.

Please tell me you didn’t write the fluid part numbers the other way around here.

It is like exactly opposite to OP?

I've edited that post and corrected it. Thanks for finding my error!

Sql, sorry about my error in posting. I would suggest double checking everything you read on this or any forum out there.

When researching the fluids I found a lot of conflicting data but by checking many sources including the factory service manual and Land Rover dealer websites for the right fluids only then did I finally buy and use them.

All information posted on public forums is. "use at your own risk." It's unfortunate but people do make mistakes and I'm no exception.

When reading this thread and you see I have conflicting information (reversing the part numbers), the fact that your car is a different year, different generation of the L322 with even a different engine should be enough to make extra sure the information is correct and applies to your car. All car companies change specs and hardware and even if I had not posted the incorrect information I would have suggested you be very careful about applying this info to your car.

Hopefully you now have the correct information and are successful with your servicing!

In the future I'll try to be more careful when posting information here.

Good luck!

Yeah, I found it crazy confusing when reading a bunch of writeups on those diff oils. Castrol this. Castrol that, LR number this or that. Also open diff this and electronic lsd that. When I found your post consisting of simply two part numbers and knowing you had facelift electronic diff car I just copied that and texted to my mechanic.

Luckily it turns out he didn’t find fluids by LR numbers and simply used correct BOT720 (but by Ravenol) and proper 75w90 in front one.

So all good and no worries! 12 4.4 TDV8 Vogue

Hi Sql,

And just to be clear, there are three generations of the L322. I think it's 2002 - 2005, 2006 - 2009 and 2010 - 2012. Different engines in each generation but I don't know about the rest of the drivetrain.

Glad it all worked out!
