Replacing differential fluid 900

AFter considerable effort I was able to crack the refill bolt and lower bolt in the differential. Tommorrow I will drive the car a bit to try to get the oil in the differential warmed so it will flow better, and will remove the lower bolt in the differential as mentioned at this site to drain it. If I remove just the lower bolt at 6 oclock will that allow it to drain well?? or do I have to remove several of the lower bolts?? I have 2 1qt bottles of Mobil 1 75-90 oil to replace it with. Thanks JOHN

Replacing differential fluid 900

Just remove the lower bolt and the fill bolt at the same time and it will drain. If you're not in a hurry, you really don't need to get it hot to drainit, that's basically for shop situations when you need to get done quickly, if you've already got it on the jacks, and aren't planninmg on going anywhere for awhile, just go ahead and open it up and let it drain for an hour or so until it quits dripping.
