How to check and adjust the steering wheel toe

First, the inspection method of the steering wheel toe:

Method 1: When the steering wheel is suspended, turn the steering wheel to measure the distance between the front end of the two steering wheels and the distance between the last ends. The difference between the two is the toe value. This measurement method has a large error because there is a gap between the steering knuckle and the king pin, between the hub bearing and the steering knuckle, so the state in which the steering wheel is suspended is not the same as the state when the ground is loaded.

Method 2: Measure with a pointer-type front beam ruler. Due to the length of the front beam, the flexibility of the two measuring feet and the thickness of the two-wheel steering tire side also affect the accuracy of the measurement.

Method 3: Measured by the flat cart method. Park the car on a flat surface and mark each of the heights of the rear of the two steering wheel tires to measure the distance between the two marks. Then push the car forward, so that the two steering wheels rotate 180 degrees, that is, turn the mark to 1/2 of the height of the front of the two steering wheel tires, and then measure the distance between the two marks. The difference between the distances measured twice is the toe value of the steering wheel. Then push the car forward, turn the steering wheel 90 degrees, and then measure the toe value of the steering wheel as described above. Take the average of the two measurements as the actual toe of the steering wheel of the car. It is also possible to take several points on the tire for measurement to eliminate the influence of various factors and obtain a more accurate toe value.

Second, the adjustment method of the steering wheel toe:

The adjustment of the steering wheel toe is achieved by changing the length of the steering tie rod. When the tie rod is extended, the toe value is increased; the tie rod is shortened, and the toe value is decreased. Here are the general adjustment steps:

1. Loosen the locking bolts on the joints at both ends of the tie rod.

2. In order to see the number of turns of the tie rod, it is best to use chalk to make a mark on the tie rod and the joint.

3. Rotate the tie rod to extend or shorten it.

4. After adjusting, tighten the locking bolts on the joints at both ends of the tie rod.
