Symptoms
Uncontrollable side-to-side shaking of the front end, usually triggered by a bump at around 45 mph and stopped only by slowing right down.
The fix, step by step
- Quadratec's sequence: disconnect the steering stabilizer so it can't mask anything.
- With the key on and engine off, have a helper turn the wheel a quarter turn each way while you watch both ends of the track bar for movement.
- Then jack up the front and check tie-rod ends for play, ball joints by prying the tire, and wheel bearings by rocking at 12 and 6 o'clock.
- Inspect control arms and bushings.
- Tighten every steering and suspension bolt to spec, replace anything that moves, check tire balance and pressure, and finish with an alignment.
- Off Road Xtreme says a loose lower track-bar bolt is the most common cause.
- Drivingline warns a worn, oval frame-side hole may need drilling or an aftermarket bracket.
