Yup. Sometime tomorrow or Wednesday I will double check the brakes since that was the last thing I touched. I can't imagine the brakes are causing this issue in reverse but not forward but I guess you never know.
Also going to spin the wheels by hand and see if I can replicate the noise.

Thought about that but only in reverse? Seems odd. I never touched them when I did my brakes the other weekend.

Remove the driveshaft and see if it's not the transmission? Then go back from there?

@strutaeng My thought was spin it first, if it makes noise remove DS, spin again, if it makes noise then problem is isolated to rear.

Then put a big turbo on it.

No noises except what I feel is normal brake dragging. Although I did notice that my right rear brake line has rubbed through the coating and is down to the braided part. I checked it a couple times after install but I guess I should have checked again. I will move the banjo bolt and see if that makes a difference.
Anyhow, no noises that I feel are out of place. I guess the next thing to do is start the truck and put it in reverse on the stands and see what happens. I did order new gear oil and a gasket which should arrive next week so I'll go ahead and pop it open just to double check. I never changed the gear oil on this truck when I got it.
Edit: I posted too soon. I did "drive" the truck on the stands. No issues that I can tell. Maybe some weird vibrations when in reverse and the brake is on? But it seems to do this with my foot completely off the brake. What I will do is pull the wheels and tires off and get the brakes back off and see what is going on underneath.

Thinking at my desk today, couldn't I pull the parking brake shoes off to eliminate the parking brake as a potential issue?

I was just thinking maybe your parking pawl is not disengaging only in reverse? IDK if that's possible, but just a guess. 🤷
