Rear end oil change, how?

Rear end oil change, how?
I have had my 4.10s in now for 500 miles and I believe I want to change out the dino oil and put in Mobil 1 75w 90.
Called Jiffy Lube and they said they do not remove cover, but use pump to remove oil.
Is this satisfactory? I understand that there will still be a little residual oil by doing it this way, but it's probably cheaper than having a garage pull the cover (and probably have to put on another gasket).
Doing it myself is not an option.
Thanks

What type of posi unit do you have? If it is an Auburn, stay with a natural product.
The below quote of from a DAQ on AUburn's website:
"2.) What kind of oil should be used with an Auburn differential?
It is important when installing Auburn differentials that a high quality, non-synthetic 80w90 GL-5 oil, treated with GM or Ford limited-slip additive (also known as friction modifier) be used. Three ounces of additive will treat one quart of oil."

2nd, i dont like to use the gaskets, i've had 3 leak, so i just buy a TUBE of RTV, and use that instead of the gasket...

Why is doing it yourself not an option?
It is easy, and will save you some cake.
I used a gasket but I got some gasket shellac and put it on and bolted it back up and so far, NO leak. Yayy!

well, on changing the oil, it would be best to take the cover off anyway to clean out any little shavings that the new gears may of had..

My '94 has a magnet bonded to the inside of the diff cover. Any metal shavings end up there, so its not a big concern. However, it's still a good idea to pull the cover, to inspect the gears and see how much metal shavings have built up on the magnet.
I use only RTV, no gasket. I've always had better luck this way, no leaks. BTW, Chrysler used only RTV on their valve covers for their 4 cylinder engines, applied by a robot.

Yea I agree with taking the cover off. When I did mine, it was probably the first time. I also took brake cleaner (i think) and cleaned the whole inside of the pumpkin. You'll probably notice its pretty black. (mine kinda was). Then I replaced it with Synthetic. Only after that did I also read something about not using synthetic, but hey, its still fine. And I always use the blue rtv (or whatever) to reseal any diff change I do, it just seems easier. I was surprised however, at how little oil the rear end in the f-body holds.

Well "screw it". Thanks for your replys. I know I should take the cover off, but I'd rather pay someone to just pump it out (because all the quick lube places won't remove the cover).
Well my rear only has 8 grand on it and the gears only 500 miles, so hopefully pumping it out will be ok.
So even if GM did put a drain plug in it, that would still not be as complete as removing the cover.
Hopefully there won't be any shavings in there to booger up my gears.
Thanks again for the replys.

I would be extra careful about any pitstop/jiffylube place. They aren't exactly picky went it comes to employees around here.
