When I put it in drive and start driving I feel a shake on the truck and feel in the front on the truck if I let off the gas pedal the truck drive normal and shifts fine
my front differential went out. Completely fried from what the dealership is saying. Noticed differential oil all over my front left tire then a grinding noise followed the day after the oil came spewing out. It's been at the dealership for 3 weeks, absolutely ridiculous. They have no idea why it happened on such a fairly new vehicle. Does anyone know why this would happen? Thank you.
