(2) Troubleshooting Method 1 In the cab, turn the steering wheel left or right by hand to check if the amount of free rotation is too large. At the same time, one person turns the steering wheel and the other person watches the steering linkage mechanism under the car. If the steering wheel turns a lot and the steering arm does not rotate, the fault is on the steering gear itself; if the steering arm rotates a lot and the front wheel does not deflect, the fault is in the linkage mechanism. 2 If the fault is in the steering gear, one person continues to turn the steering wheel left and right, and the other person grips the steering rocker arm by hand to judge whether the meshing gap between the roller and the worm is too large. In addition, holding the steering wheel by hand, pushing it up and down, judging whether the worm's upper and lower bearing clearances are too large or not, adjusting as necessary, and repairing or replacing damaged parts. 3 If the fault is in the linkage mechanism, one person continues to turn the steering wheel left and right, and the other person observes whether the ball joints of the horizontal and the straight tie rods are loose under the car. If it is loose, it will wear too much for the straight rod or bowl, and the spring breaks or the screw plug will loosen. If necessary, readjust or change parts. 4 Raise the front wheel with the jack, pull the tire with your hand, and push the front wheel along the inside and outside. If there is any amount of turbulence, loosen the front wheel bearing and re-adjust and fix the bearing nut. If the bearing is damaged, it should be replaced. 5 Set up the front wheel, place a stylus next to the rim, and then turn the wheel and place the stylus near the rim to see how it deforms. In general, the arch curvature should not exceed 3-5 mm. If it exceeds, it should be corrected and replaced. 6 Check if the leaf spring bolt is loose or retracted. The rivets on the front frame of the frame are loosened and can be checked with a hand hammer. If there is a virtual sound, the rivets are loosened. If the above adjustments are still invalid, the front axle should be removed to check if it is bent. If it is bent, it should be replaced. 7 Check that the tow is in compliance with the regulations and readjust it if necessary.
