At 60MPH, I hit a series of bumps traveling south on I45 towards downtown Houston. These bumps triggered the "death wobble". The violent shaking so so bad, everything on the seats wound up in the floorboards. It was all I could do to keep the vehicle in my lane. The violent shaking continued until I was able to slow the vehicle down to about 5MPH, I have been fighting this issue a couple years now, replacing part after part trying to get it corrected. I am at my wits end trying to resolve this apparent coil spring suspension design flaw.
