It started as a very light vibration sometimes on the highway.
Since it was intermittent, it was hard to know if it was the road or the coach.

Last trip out was a short one, but I noticed the vibration a little bit more on the trip home.

Then, this happened just a few miles away -

So, I decided to check the front bearings.

Pass side - The wheel turned smoothly & silently. The pink grease looked new.

Driver's side was a different scene.- The wheel turned smoothly, but I could hear a faint rolling sound. The pink grease was still evident, but is very dark inside the bearing. There was also a very faint rust trail from the spindle nut down.

Looks like I'll be replacing the bearings & seals soon.
