I have a 97 K1500 Suburban with 175K. I have noticed that I recently developed a "hollow clicking" or "metallic rattle" sound. It sounds as if it is coming from under the truck towards the drivers side, middle to rear of the truck. I can hear it driving while driving at low speeds 20 m.P.H or slower. I have found that the noise goes away if I accelerate but happens only when not accelerating. Braking does not affect the noise what so ever. It almost sounds like a loose center cap rattling, but I know that's not it. Hopefully, someone has some idea(s) and advice on what I need to be looking for. Thanks.
