Bad axle or struts or both

I bought my car used from a Ford dealer in March. I had the car aligned and had new Michelin primacy MXM4 tires put on. It had two bad front wheel bearings which is uncommon for such a new car. Even then, the car drove very smoothly.

The driver's side was replaced first. Upon removing the bearing, they noticed that the bearing had sheared the axle threads off. They replaced everything and it drove great for four days.

On a Monday morning, I got in and drove to work and I honestly thought I had a flat tire or something was obstructing my passenger side front wheel from rotating freely. Later that day, I heard the same rubbing sound that was associated with my first bad wheel bearing.

I took it back to the dealer, they replaced the passenger side bearing - there was something internally wrong with it. Nothing was said of the axle, and I went on my way.

I still feel like something is preventing my front (more so my passenger side) wheel from spinning freely. There's more friction than usual. Newly paved roads feel a bit like I'm riding on very small and tightly spaced waves. There are vibrations throughout the cabin, particularly in my steering wheel and the bottom of my seat. It's consistent whether I'm driving via electric or fuel engine. It also doesn't seem to change if I'm accelerating, cruising, or braking.

When I'm idling, (going 1-3 mph without pressing the gas) I can feel a little 'bump' every rotation on my passenger side. There isn't anything sticking out of my tire, it's definitely something internal that is causing the bump. The front passenger side tire pressure has been known to dip lower than the rest. But I check it often and it doesn't seem to be a problem anymore.

I obviously want to take it back to the dealer, but I've been in and out of there so much, I want to go back with a clear idea of what's wrong. (It took an alignment, new tires, and 2 trips to the dealer to convince the service department that a wheel bearing was bad.) Everything has been covered under warranty and I want to utilize that as much as I can.

This fact is more so for the question on the next page. I'm a mechanical engineer and I work in the automotive industry, but I can't say that I've ever fixed a car. I design and test for ergonomics, sound, and vibrations.
