Most likely a bad hub. Try turning the steering wheel right or left and see if the sound changes or goes away while turning. If it goe away or significantly changes when you turn left it is probably the right hub and vice versa when you turn the other way. If you hear a popping sound when turning it is the constant velocity joint.
check your wheel bearings.
It turned out to be the alternator going bad. Replaced alternator. No more growling.
Check your muffler pipes.
I think that they would use energy to do anything- moving, growling, etc.
A noise coming from the back of the throat, like the growling sound a dog would make.
If they get dirt in they can cause a scrubbing sound, but not very common. I would check all moving parts in that area carefully for something loose.
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
It depends on the type of bear or their feelings. It could be growling really loudly to protect its family, or just softly growling at their cubs. I hope that helps! You can always research about bears because they would definitely have their characteristics on a fact file page :P
it's the air intake taking more air and the belts moving faster
Sounds like u need oil!
The ac compressor is shot. Usually what your hearing is a bearing that is moving around.
Of what?
