What are the 5 basic alignment angles?
Traditionally, five alignment angles are checked at the front wheels-caster, camber, toe, steering axis inclination (SAI) and toe-out on turns. When we move from two-wheel to four-wheel alignment, we add setback and the vehicle thrust angle into the equation. Unlike a two-wheel alignment, a four-wheel alignment will include both a front-end alignment and a rear suspension adjustment. This simply means that a professional technician will adjust any camber, toe, and caster angles on both the rear-end and front-end of your vehicle (if applicable).Most modern vehicles are going to require 4-wheel alignment, whether that’s a front-wheel drive, all-wheel drive, EVs, or anything with independent rear suspension. Basically, if you’re servicing today’s vehicles, a 4-wheel alignment is expected.Type of Alignment Service A two-wheel alignment is typically less expensive because it focuses on just the front wheels. A four-wheel alignment involves adjusting all four tires and requires more time and calibration, which is especially important for vehicles with independent suspension or all-wheel drive.Use 2-wheel alignment for trucks with fixed, non-adjustable rear geometry; use 4-wheel alignment for trucks with adjustable rear geometry, independent rear suspension, 4×4 drivetrains, or any rear-end work or symptoms. When uncertain, opt for a 4-wheel alignment for a complete check.That’s because some vehicles require specialized equipment or have engineering designs that make the job more difficult and time consuming. While performing the alignment, the technician may find that more work — like tire balancing or car suspension repairs — is needed.
What is the best kind of alignment?
The type of alignment you need depends on your vehicle. Most modern cars require a four-wheel alignment because of their all-wheel-drive systems or independent rear suspensions. Older or rear-wheel-drive vehicles with a solid rear axle might only need a two-wheel alignment. Yes, you can get an alignment before buying new tires. It doesn’t matter whether you get your alignment before or after having your new tires put on.Misaligned wheels can cause the steering wheel to pull, challenging you to maintain a straight path. This not only increases driver fatigue but also compromises handling. The critical angles—camber, caster, and toe—must be precisely set, as even slight deviations can significantly impair steering dynamics.The primary purpose of wheel alignment is to improve the car’s handling and ensure that it drives smoothly. Misaligned wheels can cause various issues, including premature tire wear, reduced fuel efficiency, and difficulty steering.Yes, it is recommended to get a four-wheel alignment when you fit new tyres. Even brand new tyres can be affected by improper wheel alignment, which can lead to uneven tyre wear, increased fuel consumption and poor handling.Yes, you can drive with bad wheel alignment, but it is not recommended. It can cause your vehicle to pull to one side, and your tyres to wear unevenly. Can bad wheel alignment cause vibrations? Yes, bad wheel alignment can cause vibrations, particularly at higher speeds.
