Hi,
I have an abnormal sound when the car is moving. It is like a heartbeat. Like a very fast heartbeat. It is not coming coming from engine. Put in neutral while driving, and noise is unchanged. No noise when stopped.
There is no vibration.
Hard to describe what it is, but I can say what is not.
It is not the humming noise specific to wheel bearings. It is not the clunking noise specific to control arms, nor the tie rod bush fail sound when turning; noise is there when driving straight.
In my older cars, a similar noise was combined with vibration, and the culprit was CV axle. A bent CV axle on one car, and damaged cage on cv axle on another car, but that was noisy + some vibrations mostly on turns.
Suspended front wheels and spun the wheels. Did not hear any strange noise, but i admit I rotated them by hand; admit I could not spin them fast.
CV axle inner and outer boots were OK. No leaks. Spun the wheels few times to see if the CV axles were bent, and as far as I could see, there were not bent, but it was hard for me to gauge the axle was not bend visually. The passenger side middle anchor bearing holding the mid point of cv axle did not have any play when i pushed it up/down-left/right. CV axles where tight when i pushed on them.
Also, when braking, there is no pulsating noise or vibration, so i would refrain from blaming warped rotors.
Grabbed the wheels at 3 and 9 o'clock positions and there was no play. Same, the 6 and 12 o'clock wiggle did not have any play, with both front wheels suspended.
Any ideas?
