Signs to have wheel alignment checked

WHEEL alignment is a suspension-tuning tool which greatly influences the vehicle’s handling and tyre wear. It comprises the measurement of complex suspension angles and the adjustment of a variety of suspension components.

Correcting a vehicle’s wheel alignment consists of adjusting the angles of the wheels and tyres so they are parallel to each other and perpendicular to the ground, thus maximising tyre life and ensuring true tracking along a straight and level road.

The primary static suspension angles that need to be measured and adjusted are caster, camber, toe and thrust an- gle. The wheel alignment of a vehicle should be checked whenever the following events occur:

• New tyres are fitted to the vehicle;

• Suspension components are installed or modified;

• The vehicle encounters road hazards that could upset the correct wheel alignment configuration (hitting a pothole, driving over a brick or curb, etc); and

• A vehicle has travelled 10 000km since the last wheel alignment inspection.

Balanced tyres can make the difference between a pleasant driving experience and a negative one, as improperly balanced tyres may lead to vehicle vibration and poor ride quality.

Whether you drive an old or new vehicle, balancing your tyres can go a long way in improving driver and passenger comfort.

Indications that you may need to have your balancing checked include:

• Vehicle vibrations at speeds in excess of 60 km/h;

• Steering wheel shudder; and

• Irregular wear of tyres, bearings, shock absorbers and other suspension components. – Source: Tyres & More
