A vehicle is said to be properly aligned when all suspension and steering components are sound and when the tyre and wheel assemblies are running straight and true. Proper alignment is necessary for even tread wear and precise steering. Uneven front- or rear-tyre wear or changes in your vehicle's handling or steering response (i.e. pulling to one side) can indicate misalignment. Many vehicles today are equipped with rear suspensions that can be adjusted for alignment. Your vehicle may need a "front-end" alignment or a "four-wheel" alignment, depending on the symptoms you are experiencing. The moderate cost of having your vehicle aligned can more than pay for itself in tyre mileage, performance and comfort. D2D retailers provide expert alignment and suspension service.

Vibration is an indication that your car has a problem that needs attention. The tyres, steering system and suspension system should be checked to help determine the possible cause and correction of the vibration. If left unattended, the vibration could cause excessive tyre and suspension wear. It could even be dangerous. D2D retailers can offer expert diagnosis and repair.

Properly balanced tyres are important for driving comfort and long tyre life. Unbalanced tyres can cause vibration, resulting in driver fatigue, premature tyre wear and unnecessary wear to your vehicle's suspension. Tyres should be balanced when they are mounted on wheels for the first time or when they are remounted after repair. Tyres should be rebalanced at the first sign of vibration or "shimmy". Vibration may also be due to misalignment or mechanical problems. Many D2D retailers can provide expert diagnosis and repair.
