Default question - steering wheel shudders

When I apply the brakes, the steering wheel shudders very noticably
between 40 and 30 mph. It doesn't happen 100% of the time, but it
happens pretty often.

Any ideas what this might be?

Why only in that speed range? The speed is very consistent - when I am
braking, I know when I have hit 40!

TIA,
Nate

Things to check:
1. Brake rotors for warpage.
(If you don't know or can't check rotors the tire shop should be able to
check them as well.)
2. Tire balance.
3. While at tire shop ask them to check steering and suspension linkages.
My guess is both 1 and 2 need attention and you may possibly have a problem
with something in 3.

One thing I forgot that is a possibility is a tread seperation in a tire.
Tire shop can check this as well.

Hmmmm....Interesting.

i have this same problem in a '94 LHS, the tires are less than 8 months
old and have less than 10,000 miles on them.

i was thinking rotors; I did the rotos about a year ago, but the shimmying
is only coming through the wheel; there is no pulsation on the brake pedal.

Then in your case I wouldn't suspect the rotors. Although not a high number,
tires can be bad when new or very shortly after. You should be able to go
back to where you bought tires and get a free check of tires, steering and
suspension components. Be careful if they start mentioning large $$$.
You can usually find a tread seperation by jacking vehicle and spinning tire
slowly. Watch for an unusual contour or bulge. Sometimes you can feel arougn
tire tread and feel the uneven place. Do a visual first before feeling
looking for wires, if the steel belt is broken it can protrude wires through
tread and will stick you. I usually feel around tread with a leather glove
on first to eliminate wires protruding.
You can also look for loose steering or suspension parts while vehicle is
jacked.

quick update...
I had new tires installed over the weekend, and the problem still seems
to occur, so I think it is unlikely a balance or tread separation issue
for me. While I was there, I asked the guy to check the rotors and
linkage, but the response was along the lines of "we do tires and
wheels here, we don't have mechanics"

I feel a tiny bit of rumbling in the brake pedal, but it is definitely
much more noticable in the steering wheel.

Thanks,
n8
