More pics as I take it apart, but I just had to catch a flatbed ride (free from AAA Premier) the last 125 miles or so back from SEMA. Wheel bearing had been noisy, and it got worse along the way to Vegas, but my experience is they just continue to make noise, and don't fall apart. By the time I made Victorville last night, it was wobbly. Snow and cold wind convinced me to not change it then, with the Timken spare I carry, but to spend the night, see what's up this morning, and then decide to use up my one 200-mile tow of the year.
It was not only wobbling, but the brakes were failing, and I could see in the light that it was tilting!
After the tow, I limped up my long driveway where I told the tow driver it wasn't necessary for him to venture.
