Talk about strange noises, my GS 300 ( 2006 ) started to rumble every now and then. No set speed at which this would happen and not on a right or a left corner just random?? The VSC light came on and the TRC came on. The car still runs fine accelerates as normal but this rumble noise just does not go away. I checked wheel balancing and all four came up zero, even changed two tires which were close but still legal. The car has nearly 200K miles on it but always serviced at the Lexus dealer last time it went in they said water pump will need replacing soon and one of the rear brake callipers was seized. Would these cause the random rumble??? Any help would be appreciated.
