Changing Diff Oil On A R33 Gts-t

[matthew0786]

Hi,

im about to change the diff oil, but i dont know where the filler hole is.

On the driver side of the diff, there is a hex shaped hole (ive tried this one, but it wont budge) and on the passenger side, theres 2 bolts that look the same (above the exhaust)

Also, ive noticed that there is a hose running from the diff into the boot. In the boot, there is a fluid reservior, i was wondering if thats the diff oil??

My car is a R33 GTS-T Series II

the fill/drain holes are not hex shaped, they have a square indent. this is a standard 1/2 inch drive shape, so a 1/2 inch socket wrench without any sockets in it is the correct tool (altho you may need a breaker bar )

the drain plug is on the back of the diff, at the bottom, facing the rear bumper. the fill plug is on the passenger side of the diff, halfway up, facing the left rear wheel (it's a bit trickier to spot). a short extension bar on your socket wrench will be needed.

always make sure you can get the fill plug out before you drain your old oil...

Sounds to me like he has a A-LSD (from the GTR vspec)

Nope not always... mine arent

Is your diff cover Finned? The drain plug is 1/2inch drive.. however the filler is on the drivers side.. Very large allen key needed with lots of leverage.. Will also most likely have locktite on it.. so will require a bang with a hammer to break the seal..

Make sure you put in a proper LSD oil as this diff is different to the normal R33 Diff..

Yeh i believe your right. i couldnt find a filler hole on the passenger side, so it must be this.

and do you have A-LSD and SLIP lights on your tacho?

IF so you've got an Active LSD.. from the GTR Vpsec
