rear differential got lube? rear wheel bearings?
Take it to a garage!
There is no opposite for intermittent action (coming repeatedly over time). The closest would be constantly or continuously, but they are not opposites.
As intermittent means occurring at irregular intervals, a possible sentence could be:Because of the rugged terrain, the signal from the telecommunications tower was intermittent, and the lost hikers had difficulty using their mobile phones to call for help.
I have the same thing on 2000 echo, I was told to put a long screwdriver on the alternator then put my ear to the screwdriver to hear if the squeal is coming from the bearing after verifying the belt wasn't the problem.
depending on how low it is, it is either the fan rubbing against the casing or the belt that turns the fan coming loose.

If the squeeling is coming from the tires, then the problem is most likely a misaligned front end. If the squealing is coming from the engine, then the problem would be in the power steering system.
Check for loose or worn serpentine or drive belts.
F.u.b.a.r.ed it ?
I know that squeals attract hogs if its coming from other hogs held a hog one time that was squealing and had about 8 come to it to help out
it could most likely be a blown head gasket
Your question is vague, but since you used the words "squealing/grinding" I first start to look at the brakes. The squealing could be coming from your brake pads. Some brake pads come with a safety mechanism that alerts to when the brake pads are nearing replacement time. If you ignore that squealing then it turns to a grinding because there ain't no brake pad left. At this point, you're now looking at replacing the rotors as well as the pads. Rule of thumb is that if one side is bad then the other is just as bad or not far behind it.
