Rear diff oil change

[B4 I was 250T]

Ok, so I watched a youtube clip on it and it seems simple but I want to run over it so I get it right. Jack back of car up, loosen top plug (filler point?) and undo bottom plug using 1/2in ratchet. Drain fluid, replace bottom plug and refill with 1.2 litres of diff oil (Motul? Castrol?) Put filler plug back in. Tighten everything up, ensure no leaks and job done. If there's anything I've forgotten please add so I don't cock it up.

sounds good, DON'T OVER-TIGHTEN THE BOLTS!!!!! I did this and cracked the rear diff housing.

also i just fill my diffs till the oil tries to overflow out the top hole.

oh and put the car on jack stands, don't rely on a jack.

What do you have to fill the rear diff up with? You don't have a lot of space under the car as you think.

Dave and I used a big syringe which worked well, but was messy. I think the rear diff takes 800ml. Damo can price you up on some FUCHS 80w90 for a great price. I recently got some from him and it was cheeeap.

OH and make sure you get the bolts right. One is magnetic and goes on the bottom.

Thanks Timmy Appreciate that. Will mark bottom one with something. Was thinking of using a syringe type method with a hose attached? The FUCHS good? I'll hit Damo up but if he can't I'll just go get some from Ripco or Supercrap lol

When I did mine recently both plugs were completely seized. Couldn't get enough leverage on my power bar to crack them. So ended up doing this, (while kneeling behind the car and watching the chassis for movement).

Remove the spare wheel and rubber drainage bung poke a longish hose through the hole in the boot and put it in the diff filler hole, i use one of those 1 litre oil containers cut in half and flipped upside down with the other end of the hose jammed in it. BOOM

That's cunning. Filling from under the car is awkward.

yea lol wtf that's really smart, I got a underground bay at work so I can get a breaker bar on anything but that's a neat trick to keep in mind.

edit: also why do subie diff's have that random star printed on them? I mean it's not cheap to get that printed on every single diff you make so why did they do that? always puzzled me.

Both of these are gold.
