The Red Box Wheel Alignment sometimes fails and cannot detect data

Four-wheel alignment is based on the vehicle's four-wheel parameters, which are adjusted to ensure good driving performance and certain reliability. The installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and the installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment. The front wheel alignment includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe.

This is the relative position of the two steering front wheels and the rear axle for the two rear wheels, which is called rear wheel alignment. Rear wheel alignment includes wheel camber (angle) and rear-wheel toe-in by rear. In this way, the front wheel alignment and the rear wheel alignment are collectively called four-wheel alignment.

First, the role of four-wheel alignment.

The front wheel alignment includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe. Rear wheel alignment includes wheel camber (angle) and rear-wheel toe-in by rear. In this way, the front wheel alignment and rear wheel alignment are collectively called wheel alignment, which is often referred to as four-wheel alignment.

The function of wheel alignment is to keep the car stable and straight, and to steer lightly, and to reduce the wear and tear of the tires and steering parts of the car while driving.

2. Under what circumstances should you do four-wheel alignment?

1. The driving performance of the vehicle has been affected (the most direct feeling of the driver is the deviation, and the direction is not automatically returned).

2. Damage to the chassis and suspension caused by accidents.

3. Abnormal tire wear (but also consider whether it is due to abnormal tire pressure that causes abnormal wear, under normal circumstances, high tire pressure will aggravate the wear of the tread, and low tire pressure will aggravate the wear on both sides of the tread; If there is eccentricity on one side, there is a possibility that the camber angle is misaligned. ）

4. The axle and suspension parts have been removed.

Data to be adjusted for 3rd and 4th wheel alignment:

1. Tilt of the kingpin: function: linear stability, steering back to the center.

2. Caster inclination: function: stability, steering back to the right.

3. Wheel camber (negative camber): function: increase the contact surface of the tire and offset the adverse effects.

4. Toe-in (front spread): function: to offset the adverse effects caused by wheel camber (inversion).

It is recommended to find a Tomahawk locator to try.

Very practical and multi-functional. In general, I feel that it is OK, and the service is quite in place. There's one thing to say about it.
