Help! I have an intermitent jerky/wiggly steering wheel problem, at all
speeds.  I tried tire rotation w/ the spare and it didn't help resolve
the problem. Also I power steering fluid is at full levels.

The car drives straight, and turns both directions ok, but if you take
the hand off the steering wheel it kind of wiggles left and right about
half and inch at evenly regular paced intervals of 2-3 times per
second.  This does not seem normal, and occasionally it makes driving
not feel safe.

Note:  It comes and goes, or perhaps is becoming more perceptible at
some times than others.

Any help diagnosing this steering problem is much appreciated.

Thank you,
Shawn.
