I have a customer with bad rear bearing that hasn't gotten louder in 18 months so I didn't change it yet. It's just "white noise" to him.

I had a front bearing go from bad to insane in less than 400 miles it was undrivable. The bearing grease was cooked out by the time I replaced it.

My front left bearing needs replacing but when I changed from my 255 summer size to my 235 winter size tires the load bearing race flipped sides and noise completely gone.

Try the spare tire if you have 255 or wider tire and you can punt the bearing more than likely.

I have at least 4000mi on mine since I put the 235 and stopped the howl in its tracks
