Car: 2007 Pontiac G6, 140k miles, well-maintained
- recently replaced all brake pads and rotors
Problem: I hear a grinding or growling sound when I'm driving. The sound starts around when I'm going 10-15 mph and continues at higher speeds.
Growling is not metallic, but reminds me of the sound of poff-road tires on pavement, but worse.
The sound does not get louder at faster speeds, but certainly increases in frequency (i.e., higher pitched "whirring" sound) as my speed increases.
- The sound is not affected by accelerating per se, but only based on the actual speed of the vehicle at the moment.
It sounds like the growling/grinding is coming from the front of the vehicle, but I cannot tell from which side
My guess: I'm thinking either a bad wheel bearing or a bad CV joint.
- To be honest, I don't know enough about the parts on this car to know which it might be.
Question: Can anyone confirm that either or both of these parts could create a growling sound that changes pitch as I increase my speed?
- I've seen other websites suggesting that both are possible, but typically they comment about CV joints having a clicking sound while turning and a bad bearing resulting in a growling sound getting louder not higher pitched.
Can I figure this out without taking it to a mechanic? (I just have a floor jack btw).
