Our Lexus has 167000 miles on it and runs great, but it seems like the front wheels/axle/bearings (?) really are loud the faster you go down the road. Is is more apparent when turning too. It's not the tires, it's like it comes from axle. There's no grinding metal on metal, but it feels like it's headed in that general direction. Anyone have any experience with this on this Lexus model?

 

Sound like your wheel bearings need to be replaced. You stated that the noise is more apparent when turning. If it loud while making a left turn then the right side bearing need to be replaced. If it is loud while making a right turn then the left bearing has to be replaced. If it is loud either left or right turn then, both bearing needs to be replaced. I just replaced the right rear bearing for my RX last week. The rear bearings are bolt on and the front bearings are pressed on.

 

Thanks for the comments. What kind of costs am I looking at for replacing the front bearings?

 

I do my own repairs, so my cost is just the part cost. But according to RepairPal "The average cost for a Lexus RX350 Wheel Bearing Replacement is between $542 and $643. Labor costs are estimated between $378 and $478 while parts are priced between $164 and $165. Estimate does not include taxes and fees." Good Luck.

 

Here is a video of what's involved in changing out a front wheel bearing. Although it's a Toyota, it is very similar to the Lexus.
