Re: Clinking noise in rear wheel.

Several years ago, after having made a change in hub caps, (I have an '84
Westy which was equipped with plastic wheel covers) to metal ones, I was
way back near the Pecos Bill wilderness in New Mexico.  I heard the same
noise, just like a marble or more accurately, a bunch of marbles.  I was
certain that I had a bad bearing, but to my relief I discovered that it
was the structure of the wheel cover itself and the way it is attached to
the wheel, by friction.

I still have the same wheel covers, and they still clink at slow speeds
(1-3 mph) but I have gotten used to them.  Your paroblem may be completely
different, but you might remove your wheel covers and see if the problem
goes away.
