w18 wheel bearing noise?

Has anyone had a w-18 front wheel bearing failure?My 2007 w18 with 35000 miles just started having a light howling noise from the front end. It does not change with engine rpm or brake application. It is most noticeable at slow speeds (10-15 mph). I took the wheels off and looked at the brakes and tried to feel any play in the hub. Both seemed fine. I contacted a workhorse dealer and was quoted $ 1488 per wheel for hub assemblies, so I am not very interested in changing them if they are not the problem. Does anyone have any suggestions or ideas for me?Thanks

Welcome , I see you've been around a while without posting.
Most times with a front wheel brg. failure the noise will increase on curves in the road . As the coach corners to the right , the left side brgs. take more load and vice versa. Do you notice a change in the noise during cornering ? If the noise is speed dependant and doesn't change in corners, could be a tire issue.
And on re-reading your post I see the 10>15 MPH , although a wheel brg noise can be heard at low speeds they will usually build as speed increases.
Read another post about a grill tube hum , but I think that noise built up as speed increased too.
