Question: What could be causing my vehicle vibration?

I bought my vehicle about 3 months ago. It's been fine until a few weeks ago. I noticed a vibration coming from under the vehicle when I'm going up hill and when I'm going around 45mph. If I'm going 55-65 it's fine but if I go down to 45 then start going back up it will vibrate until I get around 50 or so. It only does it going up hill if I need speed "like taking off" but if I'm already in route it does not do it. No transmission problems at all. Tires are good.

I am having the same issue in a way with my expedition. I had the fuel pump and fuel filter replaced the day I got it because the friend I got it from said it needed it because it had a hesitation in it when he last drove it. It didn’t fix the problem unfortunately but it was a good possibility. I am now thinking mine is something like the O2 sensor or Mass Air Flow Sensir. You may check into that sort of thing. If it has had the service engine light come on at any point, you can take it to have a hooked up to a diagnostic machinehooked up. it could read any codes that may have triggered the light which in turn will tell you if a sensor or anything needs checked or replaced.

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
