At the rate I'm currently putting miles on the deuce it will be another 45-50 years before I join this club. I think I put about 3k miles on it last year and I'm around 50k total.

Any major rebuilds in the last 200000 miles. timing chain or manifold bolts or transfer case etc etc.

Oooooooh yes. Lol, where do I start?

3 Transmissions (1st was a rebuild at 100k (that was done half-assed, and left me stranded 1k miles from home), 2nd was a rebuild at 130k from a reputable nationwide transmission shop. That blew up 30k miles later, 3rd I said F it and bought a brand new transmission from GM at 160k so far so good.

Timing chain was replaced at some point, don't remember when. A few CV axles, did replace a few manifold bolts when the cat when out because they were stripped.

Valve Cover Gaskets Did a complete valve cover gasket set since it was starting to leak a bit (didn't warp the head luckily)

Diff and Carrier Bushings my power steering rack had a terrible leak and ate right through the bushings on the diff housing and carrier, replaced all those from Outfitter Designs, now 100% better plus I replaced the whole steering rack

Then a few here and there misc things (shocks, tires, brakes, front/rear diff fluid changes)

But now I have a new problem nobody has been able to diagnose (not a driveline shop, dealer, anyone). The front diff was dropped and inspected and nothing, the transmission still in warranty was dropped and inspected from the dealer and they reported nothing was "wrong". Upon acceleration, the front end of the car makes a whining noise, as soon as you let off the accelerator it goes away. Frustrating because I know something is wrong but nobody can diagnose the problem

transfer case? it sounds like a gear wine. May be dumb or you may have tried it. But remove the serpentine belt and see if it still makes that sound.Dont drive it without the belt as your water pump wont be working, Last thing do you have the stock fan? if so is it rubbing when the engine is torqued or under a load. and you could remove the fan to rule it out. I know this is far fetched ideas But you are looking for FLY shi t Here, And a clutch fan can make some weird sounds when they go bad.
GOOD LUCK

Check your motor mounts. They are probably trashed. May or may not be related to the problem but if the engine and trans are moving around it could definitely affect the driveline and/or causing something to rub.

Edit: My transmission had never been opened up at 259K miles when I did my engine swap. Knock on some wood.

The stealership ruled out the transfer case, they inspected that with the transmission.

I will have to try the serpentine belt and I do have the stock fan. Its a starting point lol. thank you!

Oops forgot to mention those, when the power steering rack went back, it ate those bushings too. So those were replaced haha. I'll have to check them to make sure they were tightened/installed correctly. Thanks both of y'all its a starting point to locate the noise

Are your front wheel bearings all good ? could be like a playing card in the spokes on a bike.
I thought that too but it only makes the noise under load/acceleration. It dissappears when you let off the accelerator. I checked them last time I had the truck up in the air
