Hi Ray,
I had the same problem as you.
I took it into my Ford Dealer and had them replace the Alternator.
Costs me $467 after it all was done.
$202 for the Alternator,
$225 for 3 hours of labor,
and Governor Pataki's 8.25% tax.
Don't try this yourself,
unless you are familiar with pulling your axle.
The RH Axle has to come out, to make room to remove the Alternator.
