[Vwdiesel] Front end bearing noise (again)

[Val Christian]

Mark,

I'm at a loss as to what to put a pipe on, with a FWD bearing, 
where it seems everything is moving.  The noise gets significant 
at 40 mph.  Time for bluetooth car diagnostic microphones!

At the moment, I'm thinking of running down the road at 70 mph,
and stopping without breaking.  Then taking a passive IR therometer/
radiometer, and measuring the hub temperature.  My concern is that
there are other factors which could have a greater error contribution
than the heat of a failing bearing.  Slightly dragging pad, etc.
