My 99 GLE is starting to act up now. It has 36K and never a problem before
this except for body work. There is an intermittent low pitched humming
coming from the rear of the car. Rotors look good but the breaks are low
now. Any thoughts? The heat shield was hanging which some one told me may
be the cause so I took it off (it was rusting out). I think it might get
worse on right turns but maybe my imagination. The sound definitely is
present. Barings I think are fine because its not a singing.

It could be your rear brake(s) is dragging (i.e. the caliper is
sticking, or the parking brake cable is binding).

Thats what I first thought but without thinking I took it to the dealer (big
waste of $43) and they said all they could see wrong was the loose heat
shield and that I needed brakes all around.

Check your tires for wear? It could still be a bearing if the pitch changes
or it stops when you go around a corner.
Humming? Maybe it's forgotten the words? (Sorry couldn't resist)

I had a humming in a car, that sounded something like a low pitched machine
was running. In the end, it turned out to be the differential that required
to be rebuilt.
