Quick Differential Drain and Fill Question... need a new gasket?

Hi:
I store my 24 Hours of Lemons track car at a friends garage but need to place another rockauto.com order today (without being able to see the car).

Q: Are there separate drain and fill plug on the rear differential cover on my 8.8" differential?

In other words, do I need to take off the differential cover altogether in order to drain and refill the diff fluid?

From the shop manual, I see that their is a fill plug but I wasn't sure how one is supposed to drain it (remove the entire cover, loosen the bottom, etc).

I might as well throw in an extra diff gasket into my order (they are cheap enough) but if I don't have to spend extra funds, I'd rather not.

Thanks in advance for your quickie reply.
Regards,
-g

No drain plug, you have to take off the diff cover. You don't need a gasket. Just clean it good and I use ultra black RTV. Never had a leak. You can use other RTV's but I prefer the ultra black. DONT USE CLEAR RTV it will leak.

I can explain it to you, but I can't understand it for you

Or, get a suction gun to remove the oil from the fill plug.
No, you won't get it all out, but you will get at least 80-90% out.

Use the ultra black RTV for the diff cover. That's how it came from the factory. Obviously just make sure you get all the old stuff off first.
