Transmissions & Drivetrains
What could cause a pulsating vibration from driverside front area?
The faster you go the louder it gets and when car i in neutral the sound is still there which leads me to believe it is the drivetrain.
You could have a tire that is going bad, driveshaft that is failing, or a warped brake rotor. Check the tire for any signs of uneven wear on the tread. If that looks fine, you might have a tire shop inspect it anyway just to be sure. Does the vibration change when you accelerate hard? If so, it might be a driveshaft. I had a driveshaft fail that had a little vibration at normal speeds, but when accelerating or going up a hill it would vibrate worse. If the vibration gets worse when you apply the brakes while moving, it might be a the brake rotor warped. You might be able to have it turned or just have to replace it.
