I have been seeing many people post "Changing the steering damper does not fix problems with suspension and big bumps making you feel as if your fish tailing. I have a 2001 Jeep Cherokee Sport and I noticed I had some symptoms of "Death Wobble" when I would hit 2-3 decent sized potholes and begin wobbling side to side.
I went to autozone and bought a Gabriel steering damper and spent around 30 minutes whacking away at the bolts and macing myself with PB Blaster while laying under the jeep trying to get the bolts off and the damper out. a 2 man job by myself. Anyways, I drove down the dirt road that usually makes me feel as if my shocks are completely dysfunctional and causes my jeep to feel as if its about to slide off the road from such horrible side to side wobble in the front end. I was amazed, I felt absolutely no wobble and my suspension as a whole was improved beyond belief.
So to people who are having "death wobble" that is only temporary directly after hitting bumps, this is most likely your cause, but if you have constant wobbles after hitting a bump or washboard roads and it does not stop once the road becomes smooth its most likely much more serious problems with your steering components.
