4wd pop and whining noise when in 2wd

[Baddkarmaracing]

after taking my truck out last weekend with a few other guys, its popping when it is first put under load in 4wd drive, after the first time it is fine. It sounds like a slipping hub. Im guessing IWE?

i also have a noise when im driving between 25 and 60mph. It comes from the front for sure, but I dont know where exactly it is coming from, I was thinking maybe a vaccum leak but cant find one anywhere

Still under warranty?

Im not even sure lol its out of bumper to bumper but still under powertrain. Would it be covered under powertrain???

I'd take it in and see what they say. Worst case they say it's not covered and you tell them no.

I just remembered about this thread, i finnally took it to the dealer and they are telling me that they dont know whats wrong with it. they said there is a vaccuum leak but they dont know where it is from, they will let me know after a little while.

No but the whining noise fixed its self some how. Haven't put the truck in 4x4 in the last week to see if it still pops which I'm sure it does

Sounds like a bad axle or IWE.
