My question is: Do most of you check the oil level with the suspension hanging? I am sure millions of vehicles have been done this way and have been just fine.

But, in my usual "overthinking" mode, I am wondering if the rear end should be "raised up" to simulate normal ride height?

If you fill the rear end on a two-post hoist with the suspension hanging, that is one thing. If you fill the rear end on a four-post hoist, the car is at ride height as if it was driving down the road.

None of the above probably really matters, but I am curious to hear your opinions. Thanks!
Ok, my 2-cents. Given the location of the side fill plug and that the angle change from normal to full "droop" is measured in degrees, I don't think it matters at all. Was that your ultimate conclusion as well?
