Repairing the steering system requires a series of professional tools, depending on the type of fault being diagnosed and the system type. For mechanical steering systems, basic tools include wrenches, sockets, combination wrenches, screwdrivers, and torque wrenches, which are used to disassemble components such as steering knuckles and tie rod ends. Hydraulic power steering systems additionally require a steering system pressure tester, composed of a hydraulic gauge, rotary shut-off valve, and adapter fittings. This tool is used to test the power steering pump pressure (standard value: 12-14 MPa) and adjust the pressure relief valve (pressure should be maintained at 0.4-0.5 MPa). During operation, ensure the shut-off valve is not fully closed for more than 2 seconds to prevent pump damage. Electric power steering systems require specialized equipment such as the ODIS diagnostic system for reading fault codes (e.g., P160900 collision shutdown fault) and performing EPS zero-point calibration. For instance, a laser alignment tool ensures precise steering column assembly, and professional materials like Loctite 290 sealant are required for seal replacement. During routine maintenance, replace steering fluid every 20,000 kilometres and inspect all suspension bushings every 50,000 kilometres. Complex faults should be referred to authorised service centers for safety assurance.
