Loud noise at 35+ mph

I've got a 2002 Lexus LS430 with 229k on her and i just redid the spark plugs/coil pack now I'm getting a sound from the front wheels, I'm curious to know if it's a wheel bearing, hub, or control arms.. it's not rattling so I'm assuming it's not a control arm but yet again maybe at higher speeds (30mph + it begins to increase as i progress in speed). Anyone have similar issues or know a possible solution, i want to quiet it up for driving long distances, especially on the highway.

ANY HELP IS TRULY APPRECIATED IN ADVANCE!

Thanks LexusFam!

Does the sound go away when turning? A worn wheel bearing normally gets quiet when you load the bearing going into a turn. Left turn quiet indicates the left bearing is noisy, right turn quiet indicates the right bearing is noisy.

It could be something as obvious as tires or alignment.

As said it's probably a tire or wheel bearing

When my rear wheel bearing went out 30-35 was the magic number and boy did she scream. Atleast yours is front. Get on AMAYAMA and grab a Koyo Bearing, go rent a puller and have it.

Replacing another front wheel bearing tonight on my '01 UL. It's making a groaning sounds at 50 MPH now, gets louder as it warms up, and varies in pitch a bit as I go around corners in opposite directions. What is weird that happened last time, the sound appears to be coming from the driver side, but it's the pass bearing failing. Happened last time in reverse.

As others have said, it's a very easy fix if you have tools and space.
