Changing Oils, How To?

[sturb25]

Hi Stu,

Deff worth doing it your self to avoid some ham-fisted incompetent mechanic doing a sub par job on your car. Your right it happens to much and if they do do a descent mechanical job, theyv'e probably left you with a few signs that they have been there in regards to your body work ect...

Drain and filler plugs for the diffs- Drains are on the bottom and stand out like dogs balls, as for the filler im pretty sure they are on the drivers sid about half way up each diff.

Transfer case - one is on the side and the other is on the back part of it as you look at it from the rear of the car. If i were you stu i'd drain the oil out of the trasfer case, then remove the pressure line coming from the pump that goes onto the back of the box, this will drain the boot compartment cansiter and give you the chance to change/flush all the fluid in the system. Once its drained connect up the line and remeber to fill the attessa reservoir in the boot. Also you will have to bleed the attessa system if you do this method. With the cars ass in the air, start car, crack nipple on trasfer case untill no bubbles just straight fluid comes out, then lock it off, move to back diff and somehow get your spanner on the nipple above the rear diff and do the same. Drop car down and check level in rear canister while the car is running.

Quantities wise I think the diffs took about 1.5L in each and transfer roughly 2.5L. You just fill it up till a bit spills out the filler plug and its sweet.

Diff Oil- Castrol SAF-XA 75W140

Transfer case- Castrol Transmax Z

Crack the filler bolts before the drain bolts to ensure you can fill them back up again :-)

Good advice dude, dont share any of your knowledge or anything...

Not necessary for a oil change, no covers need to be removed and no gaskets need to be changed.

If you want to ruin the transfer case and then pay a hefty bill for attessa repairs yes you could, if you look at a GTR box you can see the shifter assembly is above the transfer case section of the box, pour oil into here and its going into the transfer case not the gear box....

Would this one be ok for my gearbox

Gearbox oil will be OK. Just use another brand for the diffs if you can't find the Castrol. Nissan reccommend Hypoid gear oil GL5 85W-90 for the front diff (approx 1L) and LSD (if you have a mechanical LSD) GL-5 80W 90 for the rear diff (about 1.5L) You could use something heavier for Australian conditions or Motul if you want to splash out!

The drain plug on my diff is easy enough to find.

However I think my S2 RS4 has a reservoir to store the fluid.

Anyone know if this is a diff reservoir? The diff looks like it has a pump above it.

Do you just drain it and fill the reservoir ?

Thanks

That's the reservoir for the Attessa. the stuff on top of the diff is the attessa pump and accumulator. There is a bleed nipple above the diff and one down by the gearbox extension.

Thanks, So that reservoir is for the transfer case then ?

Yeah the diff filler is on the passenger side, half way up towards the rear of the diff.

The oil in the boot reservoir looks pretty brown and a bit low, So i'm going to replace it and the front diff as well.
