How to change front gear oil in a Duramax?
Click to expand… Put a 12″-18″ long section of 3/8″ clear vinyl hose on the tapered tip of the bottle and you can easily just squeeze the oil in with the bottle held in the space above the rear differential. I cannot think of a reason to replace the front gear oil unless you use 4 wheel drive most of the time.
When to change the oil in a Cadillac 3500HD?
My 2012 3500HD just uses Mobil 1 75W-90 and this car would probably be fine with the same. Just to be safe I bought 2 quarts of the 88862624 and plan to change the oil in the diff in the next week or so at 8,000 miles or so. I like to make sure all the casting sand and goobers are flushed out. Typically keep trucks for 150K or more.
What kind of rear differential does GM use?
The only Dana I know that GM used in a rear application was the Dana 60 in some of the 3/4 ton vans a while back. Until they switched to IFS, they used the D44 (later replaced by the Corp 10-bolt) and D60 for the front axle. This 10.5 is what i know as a “Corporate 14-bolt”, and its design has been in use by GM since the late 60s/early 70s.
How much fluid to change in rear differential?
Changed the fluid in the rear differential. The amount of fluid that I removed was ~2.25 quarts, and the fluid I put back in was ~3.25 quarts. I put fluid in until it ran out the fill plug. I wonder why the difference? Used Mobil 1 75W-90 gear oil.

What kind of oil do you put in a differential?
Just put in synthetic 75w-90 oil. There’s a drain plug for both of them on the lower part of the differentials. Just drain the fluid out and then use a suction device to put fluid in the fill hole. Use liquid thread sealer on the bolts threads. You don’t say what year you have, or maybe it doesn’t matter….?
