V70 AWD Transmission: - 2003 V70R AWD rear diff oil change

Nick6262 · Aug 28th, 2022, 14:09

Hi,

I'm trying to change the oil in the rear diff in my V70R but can't seem to get my oil suction pump hose in the drain plug.

So I have two questions

1. Is this the correct drain/fill hole?
2. If so do I need smaller hose? (How small?)

Viewed from the rear

I did the bevel/angle gear without any issues

After some intense googling I found the above thread. It seems you do need a really thin bit of tube. My 6mm one was too thick and inflexible.

Ordered some more from ebay.

Thinner tube worked a treat (5 mm external diameter). It did take a fair bit of effort to suck the oil out though.

Got about 400 ml out (definitely has a leak - should be about 650 ml).
