this is a 2010 gs350, when driving I get a sound (howling) from the front end that gets louder the faster you go. sounds like it has mud grips on the front. I have replaced the tires and checked the hubs (car has 85k on it) hubs feel good and noise doesn't seem to change under a heavy load or in corners. car drives fine and struts look good (I don't see any leaks in them and car rides good) any ideas on what else to look for? before I take it to the shop to get racked over the coals

Yup, when the wheels start to sound like a prop plane flying outside your vehicle (and gets worse with more speed) the wheel bearings are shot and need replaced. In your case, the whole hub assembly
