1. If a vehicle changes its original steering performance due to collision, check whether there are any deformation of the longitudinal rod, front axle and front leaf spring of Baotou Mercedes spare parts, or whether the center location of leaf spring is invalid, so that it can be shifted.

If the steering angle range after repair, can be from the top of the front axle, check the steering arm is properly installed. If the position should not be reloaded, if the steering rocker can never be made in the front wheel, the longitudinal strain should be checked. If the steering limit screw is unadjusted so that the steering angle is unequal, it should be readjusted.
