Canesfan84 Posted February 16, 2016 Share Posted February 16, 2016 My 2008 RX350 makes a loud sound coming from the rear of the vehicle when traveling between 30-60 mph. The sound is a loud humming sound without vibration. All fluids have been checked and all at good levels. Does anyone have an Idea of what the sound could be? My kids can barely hear the radio it is so loud. Quote Link to comment Share on other sites More sharing options...
Taffy13 Posted February 16, 2016 Share Posted February 16, 2016 I would check the rear wheel hub bearings also check the tires. Quote Link to comment Share on other sites More sharing options...
RX400h Posted February 19, 2016 Share Posted February 19, 2016 I agree; have your wheel bearing checked. How many miles are on your vehicle? Quote Link to comment Share on other sites More sharing options...
jamesm182 Posted February 19, 2016 Share Posted February 19, 2016 Sounds like wheel bearings to me! Quote Link to comment Share on other sites More sharing options...
Joe Thibs Posted March 1, 2016 Share Posted March 1, 2016 It was wheel bearings on my '05. Happened around 125,000 miles. Quote Link to comment Share on other sites More sharing options...
sadclown Posted March 4, 2016 Share Posted March 4, 2016 It's definitely the wheel bearing. Same thing happened to me a few months back. Quote Link to comment Share on other sites More sharing options...
