How To Easily Change Rear Diff Oil - VW Amarok 

Hi mate, Are you sure you got it right in the description about the oil that goes into the manual transfer case?? Penrite ATF BMV you have,but when I looked it up on the their website it says it's for automatic transfer cases?

Hey Ben, thank you for your information. Can you tell me from where you got that? In Germany everywhere they say you are only allowed to use special VW oil in all the 3 places?

Would also like to confirm this is the correct pil for manual amarok transfer case, need oil tomorrow morning first thing!!

If you do a transmission service on the ZF8HP transmission (the automatic one) it's generally a good practice to go for the original ZF filter. After markets filters have the tendency to have less layers of filtering material build into it which leads to an inferior filtering quality. There is a high tendency that the fitment is also not 100% correct which can cause leaks as well as improper suction from the pumps POV.

Thanks Kurt, yeah that's why I made this, went to look and found nothing. Will do!

Also thought that I’d share if you have the same model CDCA 2012 120kw Amarok as I, there actually isn’t a drain plug for the rear diff. So the two options to remove the oil are to either; suck it out via the fill hole, or undo the nine 13mm bolts and lever from the side. I ended up doing this method so I could give the inside a proper clean.

@@cmart0189 That's a bit annoying, thanks for letting us know! I definitely would do what you did, would be hard to syphon all the old oil out properly.

Here’s a bit of info: A differential / axle breather serves the important purpose on a 4WD vehicle of venting the air pressure in your drivetrain assemblies such as differentials, gearbox and transfer case. When these assemblies heat up under normal operation the air inside expands increasing the pressure and needs to be vented to atmosphere. When the drivetrain assembly cools down the air inside contracts and creates a vacuum.Many drivetrain assemblies are fitted with a breather from the factory. The factory breather is usually a one-way valve mounted directly to the axle housing or remotely on a short tube. The shortfall with the factory breathers arises particularly when driving through water crossings where the drivetrain assembly will cool rapidly creating a vacuum. This vacuum will close the one-way valve tightly shut causing air to be instantly drawn into the assembly through the axle/shaft seals. However because the seals are probably still submersed below water the water will be drawn into the drivetrain contaminating the oil and possibly damaging drivetrain components or your Air Locker.

@@bensanfordmedia makes perfect sense. Thanks for the detailed reply!

Thanks Iasone! I wouldn’t suggest just doing the rear, always a good habit to do both. Definitely a bit more effort to do the front though. I’d change transfer oil while you’re at it too.

Thanks Charli, definitely will do! Some 4x4 stuff on the tracks and modification, servicing things as well.

Yeah sorry about that, bit slower for you guys to take the whole housing off 😔

@@bensanfordmedia Mean looking Amarok tho my one still stock :/ btw what size tyres are you running atm 32s ?

@@begilmezz thank you! Just added a bunch more bar-work since this video, I’ve got 285/70/17s which is 32.7 I think.

Thanks! Haven't made one sorry, crossmember and bash plate make it a bit harder to access.

Generally every 50-75k I believe.
