It looks like you're on your way to addressing your wheel bearing already. The Powertrain limited warranty does cover wheel bearings, per a dealership diagnosis and evaluation to verify that the concern was caused by manufacture defect or workmanship, and I've included a full list of covered components. Hope it's helpful to you, and if I can be of any further assistance please let me know!
