What You Need to Know about Front End Alignment

A front end alignment is also commonly called a four wheel alignment. The reason for this is that adjustments can be made to the rear end of the vehicle. Front end alignment literally aligns the direction of the wheels for pointing the vehicle in an absolutely straight line. There are three key expressions used with reference to the vehicle and its position. These are ‘caster’, ‘camber’ and ‘toe’.

If the front tire is aligned towards the centre of the vehicle, it is called ‘toed in’. In the same case, if the front tire points outwards, it would be referred to as ‘toed out’. In both circumstances, it can put a damper on the stride of the vehicle and its tires. A camber problem occurs when the top part of the tire is inclined towards the centre of the vehicle, or away from it, causing problems in the wheel and leaning of the vehicle in one direction.

The measurement of the association between left and right tires is called caster. A caster problem is caused by misalignment between the two. For equally balanced distribution of the tire weight and the wheel, small lead weights are attached to the wheel and a machine keeps a check on the balance between the two. An imbalanced tire is probably the sole reason for problems in the front end of the vehicle. Re-balancing of the wheel would fix this inconvenience, and if left unchanged it might cause severe accidents. Sometimes, unbalanced tires cannot be fixed but need to be replaced by a new tire.

Your Guide to Tire Alignment

A first and basic point to be grasped is that tire alignment is often confused with wheel balancing. These are two extremely different circumstances. In the simplest of words, tire alignment consists of regulating the tire angles so that they are at right angles to the ground and analogous to each other. The major advantage of this regulation is that the tire life exceeds to a maximum point and the vehicle remains in a straight line while driving on an even road.

Wheel balancing, however, controls vibrations and lets the tires spin without any problems. This may be controlled by placing lead weights in appropriate places upon the wheels or the tires to adjust any major vibrations being caused in the steering of the vehicle. There are many indications of tires that are out of alignment: jagged tire wear, roving in directions other than straight, and drifting to sides while on a straight and even road. An unbalanced tire may also cause vibrations in the steering, seat or the floorboard, but that depends on certain speeds. Clear indications of needing a tire alignment can be judged by the wear patterns on the tire itself.

The best thing to do, however, is to have your tires checked periodically to avoid any kind of strain on the tires. According to technicians, the most profitable kind of alignment is four wheel alignments which allow them to recognize any wearing problems on the tires and to cover them with modifications made to the front of the vehicle.
