if this is front wheel drive you may have a CV joint getting bad

This doesn't sound good....grinding when you put torque to the motor. Where's the grinding coming from? Sounds like the final drive in the transaxle or the sun gear in the OD. Depends on whether it does it just on the highway or all of the time....could also be a bad locking torque converter. Wish I could be of more help...limited info here. Good luck.
