The front beam of the front wheels is to make the distance between the front ends of the two front wheels of the car less than the distance between the rear ends. The difference in distance is called the front beam value. When you look down from the top of the car, the left and right front wheels form a "figure eight" shape with the opening toward the back.

Front beam adjustment The front beam of the front wheels can be adjusted by changing the length of the crossbar. Adjustment can be based on the measurement position specified by the automobile manufacturer, so that the difference between the front and rear distance of the two wheels in line with the specified value of the front beam, the general value of the front beam between 0 to 12mm is normal. If the car cross tie rod is flat, you can first loosen the locking bolts of the joints at both ends of the cross tie rod, and twist the cross tie rod with a pipe wrench to lengthen or shorten the cross tie rod. When the tie rod is lengthened, the front beam value increases, and when the tie rod is shortened, the front beam value decreases. Until the front beam meets the standard, tighten the bolt.

If the car cross-tie rod is bent, in the adjustment can not rotate the cross-tie rod, but should rotate the cross-tie rod at both ends of the pull head. And because the left and right ends of the thread pitch is different, so in the adjustment should first rotate a side of the cross tie rod connector, if the rotation of a circle will exceed the value of the front beam and return a circle and can not meet the requirements, you can then rotate the other side of the tie rod connector, with the adjustments, until it meets the requirements. After adjustment, tighten the locking bolt.
