03 V6 shaking issue

I have an issue with my car, something on the front end pass side by the suspension, that I can't seem to figure out what the problem is. I've listed below all the symptoms and what I've checked to find the issue.

- The car at random speeds will shake and I hear a humming coming from the front passenger side. Sometimes it will happen at 70mph, sometimes 50, but always random, not always the same speed. This makes me think it has nothing to do with balance of the tire as an out of balance tire will make noise or shake at always the same speed.
- Sometimes when I'm taking off, I feel a heavy amount of resistance, but there is no pull in one direction or the other.
- When braking, there is no pull one way or the other.
- When the front end is pressed down, the car returns to exactly where it originally was, which makes me think it's not a shock issue.
- I took everything apart today to get to the wheel bearing and the wheel bearing appeared to be in perfect condition. Spun freely and without any noise. It also did not shake when shook.
- Brake pads seem to be wearing evenly telling me it's not a brake issue.

Anyone have any ideas? :runaround:
