Trouble w/ 05 Tundra

Need help bad!!!

2005 Toyota Tundra Crew Cab V8 2wd w/ humming sound coming from the front driver side area near the wheel. The noise starts at around 30mph then as speed increases so does the tempo of the humming noise. Sounds like a low tire would sound. So far to try and fix it the wheel bearing has been replaced and the tires have been rotated. Neither helped with the noise. Any ideas on what it might be and where I should take it?

Also on the same truck I have a very high pitched ringing noise that comes from the rear passenger side of the vehicle when driving 65mph or faster. Any ideas on what it might be and/or where I should take it?

 

One... air pressure correct?

Two... Does it change when on different pavement concrete vs asphalt..

There... Could be tires, balanced correctly or been force balanced..

Four.. you check your ujoints on the driveshaft and check center bearing..

Five check brake pads and rotors if they are worn.. ..

 

Thanks Mike
