I'm having a weird front end vibration that really isn't noticeable until 50+ MPH and it pulsates about once per second at 70mph. It only does it in a straight line and when turning left. If I barely turn the wheel to the right, the vibration is gone. I've already ruled out wheels and tires as being the problem, and I can't find anything that the wheel might be rubbing on. I'm suspecting it has to do with the front passenger wheel, but as of now I'm stumped as to what it could be. Anyone else have this problem before or have any ideas? Thanks in advance.

 

Wheel bearing? Mine was similar to what you describe except it wasn't really pulsing just vibration. When I jacked up the car I could feel a very slight bit of play in the wheel when rocking it along the vertical axis.

 

Sounds like a wheel bearing. Make sure your wheels are balanced too. Alignment? Could be a lot of things. Check for play in your wheel bearing.

 

Swapped out the passenger wheel hub and the vibration is gone! Thanks!
