Girl next door has a 2010 Chevy Impala w/31k mi. Has a buzzing noise from LF while traveling. Please note this is not a clunking CV joint, so don’t tell me that. Not a wheel bearing, okay.
This occurs while traveling straight at 20 and up. I jacked LF up. Noise very noticeable on left while in forward gear, but not reverse. Noise more audible in cabin than outside. In neutral, spun wheel by hand, no noise. Compared right side, same tests, no noise.
New brakes last year. Brakes look real good as do rotors. Consulted three mechanics, none have ever heard of this before. They think I’m nuts and I prolly am.
