    Do it yourself it is easy with basic hand tools. Drain and refill the front, on the rear I removed the cover, cleaned and reinstalled with new gasket and refilled in about one hour.

    I went with Amsoil 75w-90 Severe Gear in the front and rear.

    Anyone with a 96 Impala with a 383 can do it, I use to have one myself. Man I miss that car.

    I know in TN, the 50K service includes the differentials, transfer case, and the transmission and is $700.

    For the diffs, can you use any 75W90 gear fluid or does it need non-slip additives?

    Thanks,
    Todd

    You can use any 75w-90, I would recommend a good synthetic: Mobil 1, Amsoil. etc... no additives needed for the rear end.

    Dang we did. I used the GM Blue All Wheel Drive Fluid. I am not sure what the correct name or part number is. 2 quarts and actual will be able 1.75 quarts before it starts to run back out of the fill hole.

    Hope it helps.

    Re: Front & Rear differential & transfer case service

    I have decided to tackle this job on my own. Can anybody who has done this tell me if the rear differential has a drain plug or do I need to purchase a gasket? Have not been able to get under the truck due to the weather.

    Thanks-

    No drain plug just a fill hole. I replaced the gasket but mine probably could have been reused. I replaced anyway since I had already bought one. Got it from Autozone for around $35(Felpro rubber). I pulled the cover entirely and cleaned it off, there is a magnet attached to the cover and it had metal debris attached to it. Clean it off well with brake cleaner, installed new gasket and refilled. Should hold almost 3 quarts. Buy a hand held pump to make refill simple. I got the pump at Autozone as well for about $10.
