Wheel Alignment- Types & Procedure
Alignment refers to an adjustment of a vehicle's suspension to influence the direction and angle of the tyre’s contact with the road surface.
The purpose of these adjustments is to reduce tyre wear and to ensure that vehicle travel is straight and true.
Types of Wheel Alignment-
Mainly there are 3 types of alignment-
1. Front end Alignment-
Front end alignment refers to an adjustment of a vehicle's suspension for proper angles.
Basically, Front end alignment focuses on the front two wheels while a wheel alignment is on all four wheels.
Technicians can help that whether your only front wheels need to be aligned or all 4 tyres need to be aligned.
2. Thrust Alignment-
The purpose of the thrust angle is to determine if the rear axle is lined up with the center of the vehicle, as well as the front axle.
The thrust angle can determine the straight-ahead position of the front wheels. So ignoring this angle can undermine even the most accurately aligned front suspension.
3. Four-wheel alignment
A 4-wheel alignment refers to adjusting all four wheels, which is typically required on all-wheel-drive models, with independent suspensions.
This may include a front toe and caster adjustment, just like the front end alignment, while the rear wheels receive a toe and camber adjustment.
Procedure of Wheel Alignment-
1. Wheel alignment is done using an alignment machine that measures your wheel angles.
2. Inspect steering and suspension system, including tyre condition and air pressure.
3. Place the vehicle on alignment rack, mount and calibrate sensors.
4. Print out initial alignment settings.
5. Adjust camber, caster & toe angles.
6. Print out final alignment readings.
