Popping noise in reverse

[Sethf13]

I recently bought a 2014 Sierra slt 5.3 with about 100k miles. When I drive in reverse I can hear a popping/creaking noise constantly. But this doesn’t happen when in drive. I’ve read a few things saying it could be a CV axel. Any other ideas or does that sound right?

Service the rear brakes. IE clean and lube just to make sure they are not sticking.

 

Also clean the rear leafs and even spay some silicone spray in the groves. That's how I kept my 2014 from making noise from new.  

 

Also that year of truck had issues with the axle bolts not being torqued right on some trucks may want to check that to.

 

Just my thoughts.

Thanks, I’ll try that out this weekend
