CarFactBook Diagnostics V2.3

Start with what the car is doing.

Choose a symptom and, when possible, an exact vehicle code. Work through structured observations first, then compare them with reviewed owner evidence. CarFactBook does not invent a diagnosis or rank a failed part from unsupported anecdotes.

Structured checks

Work through observations, not guesses

0/2 checked
Safety first. If vibration is severe, steering control changes, or a tyre/wheel appears damaged, stop driving and have the vehicle inspected.
Check 1

Does the vibration happen while the vehicle is stationary?

Stationary versus road-speed vibration is a useful first split.

Check 2

Does vibration change with road speed?

A speed-related pattern is useful evidence for wheel/tyre/driveline inspection.

These checks organize observations and safety decisions. They are not a substitute for manufacturer service procedures or a qualified diagnosis, and CarFactBook does not assign a failed part without supporting evidence.
