Violent steering wobble at speed (death wobble)
Safety or reliability risk. Fix promptly.
Symptoms
Sudden, violent shaking of the steering wheel and front end, usually triggered by a bump at 40 to 55 mph. Only stops when you slow right down.
Likely cause
A combination of worn front suspension and steering joints, most often radius arm bushes, Panhard rod bushes, a weak steering damper, loose swivel bearings or worn track rod ends.
Suggested fixes
Listed roughly in the order most owners try them.
- 1
Replace the radius arm bushes
The front radius arm to chassis bushes are the most common culprit. Fit OE pattern rubber or quality polyurethane bushes and check the arms are not bent.

Replace the Panhard rod bushes
Watch the Panhard rod while someone rocks the steering wheel. Any lateral movement at either end means the bushes are finished.

Fit a new steering damper
A damper only masks the problem but a dead one lets a wobble build. Replace it once the joints have been sorted.
