Okay I`ve wanted to do this for a while. I had to get my tools out to fix a fuel leak in Bullpitts car so I thought why not? I used: An inch and three sixteenths ( 1 - 3/16 ) socket, half inch drive ratchet for the filler plug. A 15 mm Ring - open ender for the drain bolt A suction pump to put the oil in ( see pics) I put the car up on jack stands, it has SSL`s and even my spoofy lowered car ramps won`t go under the rear on flat ground. Next time I`ll do it on the slope of the driveway and get the diff more level. On the stands it wasn`t too bad but a smidge of oil stays in the diff. No biggie. First pic shows what you`re up against with sedan versus Ute.. That barge arse IRS cradle. Access is restricted somewhat. Next pic shows you the Filler plug, mine was`nt real tight at all eh. As stated it was 1-3/16`s socket. The drain bolt is obviously at the bottom of the diff rear hat, that's the alloy cover, and it seems to be the only one that's 15mm, the others are smaller. Whip that out and have your receptcle handy. It`s only 2 litres or so so it doesn`t roar out. Go check the forums for some internet argueing while it drips out for a while, beverage or sanga would be optional. Here`s what I bought for the job. The oil was.. I forget how much you`ll have your brand you`ll wanna use. The suction pump is a famous Toledo ( says so on the box eh ) brand and cost me the princely sum of 29.99 at Supercheap. Now.. I poured what came out into a milk bottle, I put that amount back in with the suction pump, it didn`t run out the filler hole but I inserted my lil finger ( settle ) and it was right there. If you wanna put a tad more in and have it run out by all means be my guest. Here`s what came out, it wasn`t too black, it`s just the residue of oil changes past and grass and sh!t from the drain pan sitting behind the shed. Put every thing back on the way it was when you removed it, including the diff tag. One day in 40 years some hapless schmuck will be restoring you car and thank his lucky stars its there. Maybe.
