My dad is experiencing "popping noises" from his 99 ML430 at low speeds and only in certain situations (like a turn while crossing a raised surface, like edge of driveway). He doesn't think it is suspension, but who knows?

Had the ML to the dealership the other day - they replaced the rear cargo door latch with a 2001 model (beefier), but noise still occurs. The technician with the "best ears" is on vacation; will return the ML for his examination when he returns...

In the meantime has anyone observed/repaired/experienced a similar problem? Could it be in body panel fittings, door jambs, etc.? Just trying to help....

Thanks.
