I have a 2001 Corolla CE (approx 95K miles on it). Recently took it in for work because of rough idle, when I got it back, the idle was fine, but it started making a "clicking" type noise every now and then when I would slow down (not necessarily applying the brakes). Now the noise has gotten much worse instead of better. It sounds like a turkey's "gobble" every time I slow down (again not just when applying brakes), and sometimes even when I'm just driving slower than normal (thru parking lots, etc). It's very loud, and the noise speeds up/slows down with the car. The slower I go, the slower and deeper pitched the noise is. Any ideas on what might be my problem?
