Greetings, all. I have a question that I think I know the answer to, but I just want to see what everyone else does. When filling the rear end of a GM product (like a 1965 GTO, for instance), I realize you use the side fill plug and fill until the gear oil drips out. That part is simple.

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!
