• Damage to steering or suspension components (Chapter 1A or 1B).

Wheel wobble and vibration

• Front roadwheels out of balance (vibration felt mainly through the steering wheel) (Chapters 1 and 10).
• Rear roadwheels out of balance (vibration felt throughout the vehicle) (Chapters 1 and 10).
• Roadwheels damaged or distorted (Chapters 1 and 10).
• Faulty or damaged tyre ("Weekly Checks").
• Worn steering or suspension joints, bushes or components (Chapters 1 and 10).
• Wheel bolts loose.

Excessive pitching and/or rolling around corners, or during braking

• Defective shock absorbers (Chapters 1 and 10).

• Worn or damaged anti-roll bar or mountings (Chapter 10).

Wandering or general instability

• Incorrect front wheel alignment (Chapter 10).
• Worn steering or suspension joints, bushes or components (Chapters 1 and 10).

Excessively-stiff steering

• Lack of steering gear lubricant (Chapter 10).
• Seized track rod end balljoint or suspension balljoint (Chapters 1 and 10).
• Broken or incorrectly-adjusted auxiliary drivebelt - power steering (Chapter 1A or 1B).

Tyres worn in centre of tread

• Tyres over-inflated ("Weekly Checks").

Tyres worn on inside and outside edges

• Tyres under-inflated ("Weekly Checks").

Tyres worn on inside or outside edges

• Incorrect camber/castor angles (wear on one edge only) (Chapter 10).

• Excessively-hard cornering.
• Accident damage.

Tyres worn unevenly

• Tyres/wheels out of balance ("Weekly Checks").
