2003nmaking grinding noise when accelerating

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. My initial guesses from your symptoms -- without getting to check the vehicle first hand -- would lean towards to the all wheel drive system or axles. Rear differential clutch issues, transfer case issues (all wheel drive models) or axle problems. No matter what, you can't drive the vehicle and need to have it checked straight away.
