Is it possible to check the fluid in the differential 04 Buick Rainier v8?

Asked by InspirationalDreamer... May 29, 2023 at 04:54 PM about the 2004 Buick Rainier CXL AWD

Question type: Maintenance & Repair

I just bought an 04' Buick Rainier and it has started making noises that sound like a playing card is
in a bicycle's spokes and I was told to check the differential fluid. I have no idea how to do this.  
Any help or guidance would be greatly appreciated. I always relied on someone who did all of my
mechanic work and now that person is not around anymore so I'm trying to learn everything myself
which sometimes can be difficult. Thank you for any help you can provide.
