front end grinding. on 1998 Chrysler Town & Country

I have a 98 chrysler town and country all of a sudden while I was driving the front end starting grinding bad. The brakes have been replaced. I just want to know what else it could be.

It could be several things but without being able to inspect the front end or hear the noise its hard to say. Most likely brake related, brake caliper related or even a very bad wheel bearing.
