Differential fluid change I decided to do it so it was up in the car lift I had to get the rear torsion bar out of the way it kind of blocks the half inch square plug I found it by using a second jackstand and forcing up the torsion bar give you just a little bit of slack to get a drive in there I first used Half by 3/8 reducer just a little stubby thing and then stuck a short three eights extension on it and was able to get it out they are tight. Then I have a kind of hand pump that sucks it out I sucked out as much fluid as I could and it was a mess try each time transferring it to the waste oil after I got it all out . I took a break for the night and came back out in the morning filling it back up was a lot easier as I had a pump on top of the 5 gallon bucket I used synthetic oil one thing was for sure it sure took a lot more to fill it up than what I got out of it. Put the cap back on it and cleaned it up

 

A brake bleeder works well also...you just need to put a modified drain reservoir (like a 2 ltr bottle) in place because of the amount. I used the same method to drain my SC.

 

I used this, Mityvac 7201. It both sucks and pumps in. Have a leak around one half-shaft. Sucked 1.1 quarts out and put in 1.7 quarts. So it got all out but for .3 quarts. Short wobble 1/2" extension worked good.

 

Oh yeah, those are good as well, ...
