We had put on the drive shaft onto the vehicle and afterwards it got a humming noise and started pulling to the right. We assumed it was the wheel bearings so we checked and replaced. It continues to do it. Could it be a possibility that its the drive shaft itself?
Drive shaft installment caused a humming and a pull to the right. Checked bearin on 1997 Ford Explorer
