car shaking at high speed

If your car shakes at high speed, something round isn’t round anymore, or it’s spinning like a wonky shopping trolley in aisle three.

Common culprits include:

• Wheel balance out or missing weights
• Tyre issues: uneven wear, flat spots, bulges, or separations
• Bent/damaged rims or a slipped tyre belt
• Wheel alignment, worn suspension bushes, or tired shocks
• CV/driveshaft issues (especially under acceleration)
• Warped brake rotors causing shudder under braking
• Worn wheel bearings

Start with tyre pressures and a balance/rotate, then inspect rims and tyres; if the steering wheel shakes, it’s usually front-end, if the seat shakes, look rear.

Get it checked promptly—vibration can snowball into uneven wear, longer stopping distances, and a very un-Australian lack of serenity.
