Hi Mate, S#!t easy to do. Just get your large socket ratchet and remove the drain plug. make sure your on a level surface and fill it back up till it starts to come out the fill plug hole, should be around 1.1 - 1.4 liter's from memory.
You can buy hand pumps from Super Cheap Auto to fill it back up. It only hols a small amount of oil so I do mine quite regularly because I tow. use 80-140 limited slip oil to. I use Nulon full synthetic 80-140 and the G70 additive 500ml. this limits the wear factor and you will notice it's in there. put it in first then the oil.

Hope this helps.

Cheers

BEFORE YOU UNDO THE DRAIN PLUG, REMOVE THE FILL PLUG. This is to make sure you can fill it back up after you drain it. If you dump the oil first and then discover you can't get the fill plug out it is quite difficult to fill the diff back up.

As above a 1/2" breaker bar fits in the square hole on both the drain and fill plugs, they take around 1.4l from memory.

Bods,
Very very wise suggestion Making sure it will all undo before releasing the oil.!!

Thanks mate, never had a look to see where the fill plug is, obviously it would be on top of the diff? Thanks for the help

Thanks mate that's a good tip!! Was that a drama you had? Haha

Not me, but I've heard of it happening quite a few times, then people having to try and weld a nut or something on to get it out...

Fill plug is about 1/2 way up the rear cover, it's the only big bolt there, you can't miss it

Nulon G70 stuff is good gear and have used it before on an open wheel diff. In fact it stopped a slightly weepy pinion seal but I wonder about putting a friction modifier in an LSD? Anyone have any thoughts on this.

Good point. But I don't recall it saying that it can't on the tube. I will have a look into that. I have used it for years even in my patrols and the limo worked well in them. But better to check.

Here you go can't see anything on LSD's but I did quote the wrong quantity to use in the rear diff it is only one small tube 125ml not 500ml.

Thanks mate, so why is the drain plug half way up the diff?

 

[BIG GUS]

Penrite Gear Oil 140 is the best oil for the D22 LSD
been using it for years (290000km) with no problems at all.

Thanks mate, so why is the drain plug half way up the diff?

its not. thats the fill plug. undo that one first!
drain plug is on the bottom.

140 is probably a better oil than the 90 recommended in the manual for your guys temps unless theres a part of oz thats actually cold!

Done both my diffs today and my gearbox today, piece of piss to do.did put nulon G70 additive in definitely made for smoother gear changes, and noticed it in the LSD too.

It's good gear. Every fluid in my Nav is now Nulon bar the fuel I use the diesel additive and flush also. When my timing chain got done it had no wear but was stretched. The mechanic even commented on how clean the insides of the engine was. Cleanest he has seen he said. So that confirmed its doing something.

Hey guys, finally going to do the rear diff this weekend. So I have 125ml of g70, that goes in first? Then I have nulon 80-140 diff oil, 1.4l? Just double checking. Thanks again

 

[fourocker]

Yep, that's the go, as long as the oil is for limited slip differentials and don't necessarily expect to get all 1.4 litres in, do it on a level floor and fill until it runs back out the fill hole. Don't panic if you only get say 1.2 or 1.3, I actually thought the recommended amount was 1.3 anyway, I don't measure it, just fill until it comes back out.
