3:42 rear end fluid capacity?

[LT1ZOB]

Hello everyone. For some reason, I cannot find the rear dif fluid capacity of my 19 Tahoe. I’ve tired several dealers and this info is unavailable. The fluid is the 75 85, that I know, but how many quarts? Please share if you know.

Capacity is between 4.2 - 5.5 pints depending on ring gear size. So 3 quarts will cover whatever you need.

Thank you very much for your help

Thank you for your help everyone. Used my buddy’s lift and a mityvac to change the diff fluid tonight. A little over 2qts went in. I have 23k miles on the truck, so I wanted to dump the original fluid and put in fresh stuff. The fluid was pretty dark, the plug magnet had the usual buildup, but nothing major.
