In my 2000 Z28 I have started hearing what sounds like: 'A pen being
rattled inside of an empty coke bottle' coming from the back end when
the car is coasting (under 30mph). For example, letting off the gas
before turning onto a street. 2 weeks ago I changed the rear brake pads
and since I had the wheels off deceiced to check around. I have checked
the suspension, cat back system, rear fold down seat, took out the
factory jack and still cannot find what is making this noise. Took it to
the dealer who said it may be bearings (right), which they packed and
made no difference.
Was wondering if any other camaro owner of similar year has heard any
noise like that when coasting?
Any advice is greatly appreciated!
(The only modifications I have done is the Flowmaster cat back and the
SLP cold air induction kit)
