This morning driving along in Cruise set at 70mph on a gentle downhill slope, I get a sudden vibration up through the car and steering wheel with a rumble sound. It feels like I have a puncture?

I slow the car and the noise and vibration stop when I get down to under 40mph.

Now I can hear a metallic clanking, like something hitting a wheel and a very faint vibration through the steering wheel. This is louder when I open the passenger window, pointing to the problem coming from the passenger (its a RHD car) side, front wheel. It also seems worse when tight cornering/full lock. But it does match wheel speed - tick, tick, tick. Applying the brakes does not change the problem.

I have made an appointment with my local wheel guy tomorrow so that we can get in the air and have a look at what is going on. It feels like something broke suddenly. A visual with the wheels on the car shows no obvious damage.

Any ideas? Drive shaft? Bearing? Oh.... I have wheel spacers all round, These are hub-centric spacers. Wondering if one has failed?
