80W and 75W are the same thing for all intents and purposes. Most Dyno oils are 80W90 and the Synthetics are 75W90. They are interchangeable. For fluid capacities, general rule of thumb (except for the new ones, 2000 and newer) is fill em’ till they overflow thru the fill hole, let the excess run off and then cork them up. Should be slightly over 2 quarts for front and about 1 3/4 quarts for front. Doc – Hide quoted text — Show quoted text –
Response:
I am planning on changing the oil in my front and rear diffs before I make the long drive from MS to ID. I am considering buying synthetic oil, but cannot figure out exactly how much I need. I cannot seem to find many websites that show the capacities for the differentials. The one site I did find showed 4.2 – 5.5 pints for the Rear and 3.5 pints for the Front. Do these numbers sound accurate?? If it matters, I am working with a 96 GMC Yukon with M80 rear end. Thanks, Mike

Go to www.autozone.com and punch in your vehicle information, then go to the specifications section. Or better yet, crack your owners manual! Doc – Hide quoted text — Show quoted text –

Doc, Thanks, I’ll try the Autozone website. Actually I did check my owners manual first, but it does not list capacities for the front or rear diff. All it has is the weight of the oil to use, and I have heard GM changed that from 80w90 to 75w90. Mike
