Product Description
WG9925477132 Power Steering Gear Assembly is installed in heavy truck steering linkage systems. It converts hydraulic-assisted steering motion into pitman arm output for directional control. Steering gear wear or internal hydraulic leakage may cause steering drift, heavy steering, and unstable road control.
This part is commonly used in heavy truck export maintenance, chassis repair, and engineering vehicle steering overhaul.




Product Overview
This steering gear assembly is widely used on SINOTRUK HOWO road tractors, cargo trucks, dump trucks, and engineering chassis. It supports long-haul fleet operation where steering precision and hydraulic stability are required.
