Generally speaking, the free travel in any direction from the middle position corresponding to the vehicle linear driving steering wheel preferably not more than 10 DEG -15 DEG, when the parts wear serious enough to make the steering wheel free travel more than 25 degrees – 30 degrees, indicating that free travel is too large, at this time, must be adjusted.

The steering wheel free travel is beneficial for easing the impact of the road and avoiding overdriving the driver, but it should not be too large, so as not to affect the steering sensitivity of the steering car too much, and to cause the steering wheel to swing at the left and right sides and to operate unsteadily.

(1) the main cause of the excessive free travel

(1) the steering screw bearing is loose.

The internal coordination gap of the steering gear is too large.

(3) steering shaft spline and cross shaft bearing loose.

(4) the loosening of the tie rod with loose or too large wear.

The loosening of the fastening parts of the steering rocker arm and the rocker shaft, or the loosening of the fastening nuts of the upper arm of the left steering section, or the loosening of the fastening bolts of the lower arm of the left and right steering joints.

The Baotou North Benz parts front spring U bolt loosening, dislocation or cause the steel plate spring front wheel hub bearing clearance is too large.

(2) the adjustment of the free stroke of the steering wheel when it is too large

First, check whether the connecting parts of the steering gear are loose. Such as the longitudinal and transverse rod joint is loose, the steering arm and the steering arm shaft connection is loose, the wormshaft bearing is loose, the steering shaft spline and cross shaft bearing is loose, necessary for fastening loose parts, or replace damaged parts.

(2) check whether the clearance of the front wheel hub bearing of the Mercedes Benz parts in the north of Baotou is too large and the front plate spring U – shaped bolt is loose, it should be repaired depending on the situation.

3. After the above inspection and adjustment, if the free stroke of the steering wheel is still too large, the meshing clearance of the steering gear of the Mercedes Benz parts in the north of Baotou should be adjusted.

When adjusting or checking the free travel of the steering wheel, the steering gear should be in the middle position (the car runs in a straight line). When confirming that the steering gear is in the middle position and the gear pair of the steering gear is in the middle meshing position, the adjustment is accurate.
