if all other steering-related parts are good, then a
nice rancho steering stabilizer will stop the death-wobble that's usually caused by:
1.) wheels with lots of outside offset & tal tires
2.) a 6" or higher susp. lift than changes steering geometry,
er go, the death wobble

other than that, run the bilsteins if you've got that kind of $$
if not the monroe Reflex is a great shock for 30-40k miles
