transfer case

The dealership said it was a balled tire but the air gauges measure all the same air pressure! !

That's not covered under power transmission warranty??

Okay, I'm still in contact with GM costumer care will trying my best!! Secondly should I do the dealership repair or otherwise some else like ammco ?

Thank you for your answers and advice! !

My transfer case replacement is covered under my Powertrain warrenty
