I have been struggling with a sizeable vibration felt in the floorboard and the front seats (especially on the passenger’s side) in my 2007 Nissan Sentra.
The tires on the car were in fair to good condition. There was a good bit more wear on the front passenger’s side tire than the other tires. The car began to vibrate regularly when reaching 55 mph. I took it in for a front end alignment. The alignment didn’t solve the issue; the car continued to vibrate at 55 mph.
My father-in-law, a mechanic, looked at the car and determined the wheel bearing to be the culprit. We changed it, and the vibration was gone.
But exactly one week later, the vibration has returned, again at 55 mph. I do know that the front passenger’s tire is out-of-round, and the car may need to be aligned again because of the work we did at home.
Still, I find it odd that changing the wheel bearing got rid of the problem, but only for a week. Might I be due for two new tires on the front end and another alignment? I hate to continue to throw money at a car this old and with so many miles. I’m pondering my next move and what might be wrong with the car. Any idea as to what may be wrong that we’re missing and why the vibration at 55 mph would go away with a new wheel bearing, only to come back a week later?
