(2) if the pipeline is intact, then steering hydraulic cylinder pipe fittings loose, if there is no outflow of oil pipeline system that is blocked, or the rotor and the stator with axial and radial clearance exceeds the limit, the spool, the radial clearance between the valve sleeve and the valve body is greater than the allowable range, you should remove the steering and decomposition, according to the gap with the technical requirements and check all parts of the binding surface, such as polished chrome should exceed the prescribed gap, such as surface repair, minor scratches should be replaced; if each component detection value in the detection range, it should clean the oil system.

(3) the inspection condition, the fault may be in the steering hydraulic cylinder, the hydraulic cylinder should be removed and decompose, check the dense engraved ring is damaged, the piston rod is bruised guide sleeve rupture, as the case to replace or repair measures.
