05 OB automatic 105K miles.

Noise from front left. Dealer said it was tire cupping so I rotated front to rear. Noise didn't change.

Goodyear Triple Treads with 45K miles on them.

What else could be causing the noise? Is CV joint noise always a click? The noise is related to speed (rotation).

Car rides smooth.

I realize that noises are hard enough to diagnose in person no less on the internet, but thanks for any feedback.

I had the same thing on the Impreza. It was a bad wheel bearing.

 

Not a do-it yourself job for the average guy. You need a press.

+1 to bad bearing. I've had this happen a couple times, actually. Last time, I had to have a used knuckle put on because the spindle froze to the axle.

 

Anyhoo, the most recent time I had a rumble and a squeal. I pulled the knuckle off, ordered a new bearing (and later a new spindle because the old one was murdered by the bad bearing) and took it to a shop in a box. They charged me a hour of labor to press it all apart and install the new parts.

 

Cost me about $200 total, IIRC. Maybe a bit less, plus a few hours ripping the front suspension apart (again...)
