Note that there for this year of Colorado the owners manual doesn't give a differential fluid change interval. Since the manufacturer doesn't say I do every 100K. How often do you change your differentials?

[@user-qw7xy3pj3p]

its every 6 months or 6000 miles

[@bryanbeck4399]

thanks for the video. my rear was dirty at 54k with some milk in it. fronts probably cleaner doing it soon as I get a chance. around the zr2 community they recommend checking every 30,000 miles

How did you pump the fluid up?

[@many-points]

The fill plug on the front differential was easy enough to access in this case that I was able to pour it directly in from the bottle (enough room to tip bottle up). (I stole one of the pointy tip caps from an old bottle of gear oil and screwed that onto the fluid bottle specific to the truck).
Another option is to use a pump style that allows you to keep the bottle on the ground:

How many miles should it b changed

[@many-points]

Good question. The owner's manual doesn't give a specific interval, so I just change it every 100K at the same time I do the transfer case fluid.
