sample quote:
Some trucks may experience sudden, violent shaking in the front end and steering wheel. This is often triggered when a pothole or bump is hit, and usually only occurs at highway speeds. The biggest culprit is insufficient caster. Another symptom of insufficient caster is the steering wheel not returning to center after cornering. Try having your caster adjusted to +4 degrees. (A truck that is within factory alignment specs may still experience this problem, so don't be afraid to tell the alignment shop you want +4 to +5 degrees.) Loose steering parts such as tie-rod ends, steering box, and ball joints will also contribute to this problem. Other things to check are wheel bearings, steering damper, and toe-in setting.
In short, the DSS has been reported to help in many cases, but check that caster first!
