From a parked position, my '96 Camry (184,000 miles) makes a vibrating noise when in reverse. Goes away in neutral, and usually doesn't show up in D (but it does sometimes).
Mechanic at a party said it could be the tie rods. I rotated the tires, and they seem secure.
Thought it was clattering valves, but shows up even when engine is warm.
Ideas?
Thanks,
Michael
