I have a 2001 E320 with 41,000 miles. Intermittently it has fast
rattle coming from the driver's side sounding to be near the fire wall
or under the hood. The sound comes and goes, is not terribly loud,
but is a fast repetitive noise that appears to be somewhat in sink
with the vertical movement of the suspension. I say somewhat because
the frequency or speed of the rattle appears to be faster than the
suspension could move vertically. When the rattle is occurring I get
a soft squeak when turning the steering wheel. This squeak is inside
the passenger compartment. Any thoughts as to where to start looking?

Two issues, in my opinion. The rattle may be from the fender liner that
surrounds the left front wheel - loose or damaged etc. There are also
other plastic shields down there that ought to be grasped and shaken to
check if one of them is the offender. The rattle may be related to wind
speed rather than suspension action.
Soft squeaks inside the steering column test your motivation: $$ vs.
soft squeak.

I checked for loose plastic around the wheel well and found nothing
loose. The clicking almost sounds electronic like a relay opening and
closing.
