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 :cheers:)

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... :mellow:

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.

      That's awesome. Fully serviced/full log book history for one of those cars is super rare from what I know. With JDM's like Skyline's, Supras, are quite hard to find one with full log book history. S15's seem to be somewhat of an exception, at least the spec s australian delivered models.

      R33 GTS25 NA - Stalling when vehicle is at operating temp

      By DRoc81 · Posted

      Hey all, It's been a bit since I have been able to update.  I pulled the fuel pump, first off it was a "universal" pump and the strainer was very clogged, and it was folded over on itself.  I replaced the fuel pump and all is well....  No more stalling.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Hey guys so turns out this project is going to be much bigger than I thought haha but I've done some my homework and have done a few panels on my car, but one part I can just not visualise is this. If I do a spot repair and I put filler in a dent for example and sand outside of the repair with 320 grit lets say so the primer can stick as I will only put primer on that repair and the surrounding area and then repaint the whole panel. Don't I need to make sure that I don't put primer on the old clear coat? I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down, it's still shiny. I thought putting paint on clearcoat or primer on clearcoat is a bad idea because it won't stick. So in this scenario it's a bit different to mine but imagine someone doing a spot repair and only painting that small section of repair but the new paint is landing on the old clearcoat. What am I missing?
