Noise from wheel! Help!

My wife has a '96 Corolla and there is an intermittent sound coming from the front right wheel that is like a chain dragging, gets a bit worse upon braking but is only there on occasion. Any ideas? Thanks!

Take it off, check it out, put it back on and see what happens

could be your brake pad is worn out and could be also your cv joints, the only thing for sure is to inspect it.

sounds like the timing chain to me...

how do you figure it's the timing chain?

could also be the wheel bearing is eaten up
