The noise sounds like it may be coming from the rear, almost like the parking brake is stuck but I don't believe it is. I thought maybe it was a wheel bearing but it doesn't seem to do it in neutral rolling down a hill and I'm pretty sure it's in the rear, and not coming from the transmission/engine. It's actually a 1986 lesabre thanks for your help
When taking off from a stop my car makes a grinding noise, until about 5 mph
on 1990 Buick LeSabre
Have a mechanic take it for a spin, to many possibilities to guess at!
